Answer:
(2r - 8)(2r + 8).
Step-by-step explanation:
4r2 – 64
This is the difference of 2 squares so we take the square root of 4r2 and 64 and write:
= (2r - 8)(2r + 8).
-8 + -8 + -8 + -8 + -8 + -8 +-8 +-8 = -72
that's one way to solve it.
Inequalities help us to compare two unequal expressions. The correct representations of the inequality –3(2x – 5) < 5(2 – x) are A and C.
<h3>What are inequalities?</h3>
Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.
It is mostly denoted by the symbol <, >, ≤, and ≥.
The given inequality can be written as,
-3(2x - 5) < 5(2 - x)
-6x + 15 < 10 - 5x (It is the third option)
-6x + 5x < 10 - 15
-x < -5
x > 5 (First option)
Hence, the correct representations of the inequality –3(2x – 5) < 5(2 – x) are A and C.
