4x - 5y = 40
4x = 40 + 5y
x = 10 + 5/4y
The x intercept is 10.
Answer:
180-43
Step-by-step explanation:
43 and x are supplementary which means they both should equal 180
Answer:

Step-by-step explanation:
We are given an expression and are asked to find what it equals. We can see that the two square roots are being multiplied, therefore they follow the same standard as any multiplication problem, do as followed :


Since a square root and constant number are different terms, we cannot combine them together, therefore leave as is :

A = velocity / time
b) 40m/s
13m / 3s = 4.33 m/ss
Completing the square is a method used to solve a quadratic equation by changing the shape of the equation so that the left side is a perfect square trinomial.
The following equation makes more sense to solve it complete squares:
x² + 20x = 52
We have then:
x² + 20x + (10) ^ 2 = 52 + 100
(x + 10) ² = 152
Answer:
The most sense to solve by completing the square is for:
B) x² + 20x = 52
