Answer:
re write this correctly..
(200 x 3) + 900
then do the steps in order.
200 x 3 = 600
add the extra 900 etc
600 + 900 = 1500

2πr² is the equation to find the base, but the answer doesn't ask for the exact awsner, rather the expanded version. 4 is the radius, radius x 2 is 8.

Answer:
x = (9/2)√2
Step-by-step explanation:
The ratio of leg x to the hypotenuse 9 is equal to the cosine of 45 degrees:
cos 45 degrees = x/9
To find the value of x, multiply both sides of this equation by 9, obtaining 9*cos 45 degrees, which comes out to x =9(1/√2). Rationalizing the denominator, we get x = (9/2)√2

Answer: 3x - 4y = 40</h3>
======================================
Work Shown:
y = (3/4)x - 10
4y = 3x - 40 .... multiply everything by 4 to clear out the fraction
4y+40 = 3x
40 = 3x-4y
3x-4y = 40
This is in the form Ax+By = C
A = 3, B = -4, C = 40
This is not the only solution possible since we can multiply both sides by some number to scale the equation.
