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

ILL MARK YOU BRAINLIEST To join a health club, a person must pay a $75 one-time fee plus a charge of $30 per month. This situation can be presented by an equation of the form y=mx+b, where x = the fire in months and ythe
total cost in dollars. What is the value of b in this equation?
Answers
Answer: b=75
Step-by-step explanation: Given that the health club charges $30 per month, we know that this is the "m" varible. We know this because the total value changes as the value of x changes. The value of b would therefore be $75 dollars because it is a constant and a one time fee. The person joining the health club pays an amount of money per month, as well as an initial charge of $75.

use the figure below and determine the angle measures. what is the measure of angle G?
Answers
Answer:
45
Step-by-step explanation:
First we want to understand the Base Angles Theorem
The Base Angles Theorem tells us that the base angles or the two bottom angles of an isosceles triangle are congruent.
Using this theorem, we can say that angle A and angle G are congruent meaning m∠A = m∠G. We can then write both of them as x.
We can create the equation ∠N + ∠A + ∠G = 180 degrees.
Knowing ∠N and knowing ∠A + ∠G = 2x, we can rewrite the equation into
90 + 2x = 180
We can then solve for x,
90 + 2x - 90 = 180 - 90
2x = 90
2x / 2 = 90 / 2
x = 45 degrees

Answers
Answer: 87.9
Step-by-step explanation:
Since the formula is 2 x pi x radius x height, we plug the equation in.
If you use “3.14” for pi, it’s 2 x 3.14 x 7 x 2 = 87.9 (rounded to the nearest tenth)
2 x pi x 7 x 2 = 87.96 (88 rounded to the tenth)

Step-by-step explanation:
10 tacos is the better deal because
it is 0.85 cents. 0.85 x 10 = $8.50 per taco for 10 tacos while it would cost $0.90 per taco for 6 tacos
0.90 x 6 = 5.40.
