Answer:
-10+6=-4
Step-by-step explanation:
Here's why we use distributive property, so a(b+c) = ab+ac, therefore 2(-5+3) is -10+6, which is equal to -4.
Answer:
I don't know what you mean, but I will try to answer.
2(-5+3)= -10+6
Value: -4
Step-by-step explanation:
2(-5+3)=
First, "distribute" the two by multiplying it to each of the two numbers in the parenthesis.
2(-5)= -10
2(3)= 6
After you finished multiplying, you will have this:
-10 + 6= (I am pretty sure this is equivalent to what you started with)
Now, you get the answer for the equation. You would add -10 and 6 to get -4.

2a^2 + 11a + 15 = 0 factorise
Answer:
The answer is (2a + 5)(a + 3).
Step-by-step explanation:
The steps are :
2a² + 11a + 15 = 0
2a² + 6a + 5a + 15 = 0
2a(a + 3) + 5(a + 3) = 0
(2a + 5)(a + 3) = 0
Kyle can write a 300-word essay in an hour. At that rate, if he writes an essay in 10 minutes, how many words will it contain?
Answer: 50 Words
Step-by-step explanation: We know Kyle can write a 300-word essay in an hour or 1 hour. We want to know how many words Kyle would have in his essay if he wrote one in 10 minutes.
First, find how many words Kyle can write per minute. Simply do this by dividing 300 by 60, since there are 60 minutes in a hour.
300/60 = 5. So, Kyle can write 5 words per minute.
Now, simply multiply 5 by 10 to find how many words Kyle would write in 10 minutes.
5 x 10 = 50. So, Kyle can write 50 words in his essay if he writes for 10 minutes.

Find the sum of the first 7 terms of the following series, to the nearest integer.
6, 12/5, 24/25
Answer:
9.983796
Step-by-step explanation:
Every time, it becomes smaller by 5/2 (6 divided by 5/2 is 12/5.... 12/5 divided by 5/2 is 24/25)
So, the first seven terms are 6, 2.4, 0.96, 0.384, 0.1536, 0.06144, 0.024756. Add them together and your answer would be 9.983796

Answer:
see below
Step-by-step explanation:
The idea is you're trying to find quotient values that get you close to the dividend value when they're multiplied by the divisor.
In the left panel, you are basically looking at 8/3 ≈ 2. Since that is 8 tens, the partial quotient is 2 tens, or 20. The value of that multiplied by the divisor (3) is what gets subtracted from 87 for the next effort.
That difference (27) is the new dividend at the top of the right panel. The line below it (-27) is the result of multiplying the partial quotient by 3. Hence, that partial quotient on the top line must be 9. We want the difference at the bottom of the right panel to be zero.
__
In case you didn't know already that 87/3 = 29, you could work backwards. Starting from 0 at the bottom right, you would fill in the boxes above that, then copy the top box in that panel (27) to the difference at the bottom of the left panel. Of course, the middle number there must be 60 for the difference to be 27. That is 3·20, meaning the partial quotient at left on the top line is 20.

Cost = $20, Price = $3 per candleChris's candles:
Cost = $40, Price = $5 per candleProfit, if equal per x candles is:
3x - 20 = 5x - 405x - 3x = 40 - 202x = 20x = 10Each will have profit of $10 if 10 candles sell

To make an equation, you need the _________ and the y-__________. If you only have 2 points, first get the __________, then use point-slope form.
Answer:
To make an equation, you need the slope and the y-intercept. If you only have 2 points, first get the slope, then use point-slope form.
Explanation:
Equations written in slope-intercept form (y=mx+b) require two pieces of information: the slope and the y-intercept, which is where the line crosses the y-axis. Point-slope form also involves the slope, which can be found from the two given points.

Find the remainder using: synthetic division/substitution OR long division:
f(x) = 3x3 - 4x2 +5x-7 : (x-2)
0-57
Oo
O 11
O-25
Answer:
The remainder is 11
Step-by-step explanation:
Here, we want to find the remainder by using substitution
We start by equating x-2 to 0
x = 2
Substitute the value of x in the function
3(2)^3 - 4(2)^2 + 5(2) - 7
= 24-16+ 10 - 7 = 11
Find the total surface area of this triangular prism.
17 cm
8 cm
2 cm
15 cm
Answer:
200cm²
Step-by-step explanation:
Total surface area of the prism = bh + L(s1+s2+s3)
b is the base of the triangle = 15cm
h is the height of the triangle = 8cm
Perimeter of the triangular base = s1 + s2 + s3 = 8+17+15
Perimeter of the triangular base = 40cm
L is the lateral height = 2cm
Substitute the given values into the formula;
Total surface area of the prism = 15(8) + 2(40)
Total surface area of the prism = 120+80
Total surface area of the prism = 200cm²
Hence the total surface area of the prism is 200cm²

Nixon estimates it will take him 5 hours to finish an art project.It actually takes him 320% of the time estimated.How many hours did it take him to finish the project?
Answer:
16hours
Step-by-step explanation:
Amount of hours Nixon took = 5hours
If it takes 320 % of his time, then he took him 320% of 5hrs to finish
This is express as shown
320% of 5
= 320/100 ×5
= 320/20
= 16
Hence it took him 16 hours

Step-by-step explanation:
because the three sides are congruent, what foes that make each angle measure according to the equilateral triangle theorem.
a 30 degrees
b 90 degrees
c 180 degrees
d 60 degrees
Answer:
60degrees
Step-by-step explanation:
Congruent means equal and equilateral triangle also means a triangle which has three sides equal.
So 60 degrees is the sides for each angle since when they are added they all add up to 180°
<AC=60°
<CB=60°
<AB=60°
60+60+60=180°
∆ABC=180°
