Answer:
<h2>
r(x+2) = 2x² + 3x - 1</h2>
Step-by-step explanation:

Make x the subject means you need to solve for x
y = ax^2 solve for x
divide both side by a
y/a = ax^2/a
simplify
y/a = x^2
so
x = square root (y/a)
It 7 500 000*m* is equal to 7500km therefore it is greater than 750km, however if youbare not talking about meters then the answer might be no.
6y > 8 - 5
6y > 3
y > 3/6
y > 1/2
Use the FOIL method to multiply these terms. Multiply the first, outside, inside, and last terms:
(5x - 4)(2x - 5)
(5x)(2x) + (5x)(-5) + (-4)(2x) + (-4)(-5)
10x² - 25x - 8x + 20
10x² - 33x + 20
The area of the rectangle should be 10x² - 33x + 20.
