Let’s start with Y
Y= -2x+4. Which is positive 2x
Now 3(2x)=x-2
We still don’t know the numeral of X
3(2x)=6x
6x= x-2
Therefore your answer would be 6x=x-2

Answer:
x=5 , x=4, x=2
i got this answer by setting the x-5=0 then solve for x. same for each x-5, x-4, x-2.
The second piece would be 28 cm.
You could solve this by subtracting 7 from 63 first. Next you divide it by two one piece is 35 and the other 28.

Answer:
D, B, B
Step-by-step explanation:
Question 1: D
We need to solve for x.
z = 2π * (x / y)¹/²
z = 2π * (x¹/² / y¹/²)
z = 2π * (√x / √y)
z = √x * 2π / √y
√x = √y * (z / 2π)
x = y(z /2π)²
Question 2: B
(x⁵ + x⁴) / (x³ + x²)
= x⁴(x + 1) / x²(x + 1)
= x⁴ / x² = x⁽⁴⁻²⁾ = x²
Question 3: B
Let's try out A. Substituting p = 1, q = 1:
√1 * √1 = √(1 + 1)
1 * 1 = √2
1 = √2 FALSE
Let's try B. Substituting p = 2, q = 2:
√2 * √2 = √(2 + 2)
√4 = √4 TRUE so the answer is B.
