Answer 1

Answer:

2x squared - 8

Step-by-step explanation:

For this kind of equation, we use the distributive property

So in the image below I used a box method (that's how I learned it in school)

So since -4x and 4x cancel each other out, or amount to 0, we don't put anything for those. So the equation left is 2x squared - 8

The dance committee of Pine Bluff Middle School earns $ 72 $72dollar sign, 72 from a bake sale and will earn $ 4 $4dollar sign, 4 for each ticket they sell to the Spring Fling dance. The dance will cost $ 400 $400dollar

Answers

Answer: See explanation

Step-by-step explanation:

Since the number of tickets is represented by t and we're told that the committee earns $4 per ticket and also earned $72 from bake sale, then the inequality will be given as:

= 72+4t>400

The solution if the inequality will then be:

72 + 4t > 400

4t > 400 - 72

4t > 328

t > 328/4

t > 82

Answer:

72+4t>400

t > 82

Calculate the length AB

Answers

Answer:

14.004m

Step-by-step explanation:

Using the SOH CAH TOA trigonometry identity

Tan theta = opposite/adjacent

Given

AB = opposite

BC = adjacent = 20cm

theta = 35 degrees

Substitute

tan 35 = AB/20

AB = 20tan35

AB = 20(0.7002)

AB = 14.004cm

Hence the length of AB is 14.004m

C 16 square units
D 56 square units

Answers

Answer:B

Step-by-step explanation:

The answer is B because you 10*6 which is 60 then 60/2 is 30

The area of the parallelogram is 60 square units.

The correct answer is option (A)

What is parallelogram?

"It is a quadrilateral with opposite sides parallel and opposite angles equal"

What is the area of the parallelogram?

"The area of the parallelogram is: A = base × height"

For given example,

the base of the parallelogram (b) = 6 units

the height of the parallelogram (h) = 10 units

Using the formula of the area of the parallelogram,

⇒ A = b × h

⇒ A = 6 × 10

⇒ A = 60 square units

Therefore, the area of the parallelogram is 60 square units.

The correct answer is option (A)

Explain how to name a triangle using its sides and angle measures.

Answers

Answer:

a triangle using 3 sides and 3m angle measure

When classifying a triangle by its sides, you should look to see if any of the sides are the same length. If no sides are the same length, then it is a scalene triangle. If two sides are the same length, then it is an isosceles triangle. If all three sides are the same length, then it is an equilateral triangle.

The value of y varies jointly with the values of x and z When x = 4 and z = 10, the value of y is 360.
What is the value of y when x 5 and z = 12?
A. 540
B. 9
C. 153
D. 450

Answers

Answer:

Step-by-step explanation:

Joint variation is given by:

[tex]y=kxz[/tex]

Where k is some constant.

We are given that y = 360 when x = 4 and z = 10. Therefore:

[tex]360=k(4)(10)[/tex]

Solving for k:

[tex]40k=360\Rightarrow k=9[/tex]

Therefore, our equation is:

[tex]y=9xz[/tex]

Then when x = 5 and z = 12:

[tex]y=9(5)(12)=540[/tex]

The answer is A.

Answers

Answer:

x=5

From the dashed lines on the two sides of this triangle, we can see that these two sides are congruent, or equal, to each other.

In geometry, if a triangle has two congruent sides, then we can call it a isosceles triangle.

In an isosceles triangle, the corners opposite the congruent sides are also congruent, meaning, that the angle measures of this triangle are: 88, 9x+1, and 9x+1.

We also know that angles in a triangle add up to 180 degrees.

So, we have: 88+(9x+1)+(9x+1) = 180

Simplifying: 18x + 2 = 92

Solving: 18x = 90, so x=5
