The answer is a or b or c or d
We want 4/5 of a number to be 144. This means that
Multiplying both sides by 5/4, we have
Please use "write" here, not "right." "write" is "right" here, if you get my drift.
"right" is wrong in this context. ;)
Example: Most of us would see immediately that 5 is a prime factor of 50.
Write 50 as 5 * 10.
10 is not prime; it can be factored into 5 and 2.
Thus, 50 written as the product of its prime factors is 5 * 5 * 2 (answer)

≈−2.071231518
Step-by-step explanation:
12.7−xx=8.41
Multiply x and x to get x
2
.
12.7−x
2
=8.41
Subtract 12.7 from both sides.
−x
2
=8.41−12.7
Subtract 12.7 from 8.41 to get −4.29.
−x
2
=−4.29
Divide both sides by −1.
x

=
−1
−4.29
Expand
