<span>x2 − 7x + 18
is prime
there is no way you can make two numbers multiply to get positive 18 and add to get negative 7
</span><span>(x − 9)(x − 2) = x^2 - 11x + 18
(x − 9)(x + 2) = x^2 -7x - 18
(x + 9)(x + 2) = x^2 +11x + 18</span>
Answer: 3/4 i think
Step-by-step explanation:
The answer is 12cm because area (420) divided bye height (35) gives you the corresponding side 12cm.
Your answer would be:
(-x)^2 = 4(-x)+32
or
(-x)^2 = -4x+32
