4) Which expression is equivalent to (-4x+3y-5)2 ?
1 answer:
Answer:
-8x + 6y - 10
Step-by-step explanation:
first, distribute (multiply) the 2 to eliminate the parentheses to get:
2(-4x) + 2(3y) - 2(5) which simplifies to:
-8x + 6y - 10
since the above expression has three terms, none of which are 'like', this is as simplified as it can be

Step-by-step explanation:
Given That:
R = 8x+4y
X= 8
R = 30.
So, 8 x 8 +4y = 30
Simplify, Rearrange and solve.
64 + 4y = 30
4y = 30/64 = 15/32
y = 15/32 divided by 4
y = 15 / 32 x 1/4
y = 15/(32 x 4) = 15/128

Answer:
x = -3
Step-by-step explanation:
Given expression is,
(4x - 6) - 4x² = -2x(2x - 3)
4x - 6 - 4x² = -4x² + 6x
4x - 6 = 6x
6x - 4x = -6
2x = -6
x = -3
