Answer:
(x+11)(x-2)
Step-by-step explanation:
To factorise: x^2+9x-22
You must first divide the centre term in such a way that the sum of the 2 values will be divisible by x squared and minus 22 respectively.
So x^2+9x-22 = x^2 -2x + 11x - 22.
Now factorize x^2 - 2x and 11x-22 individually.
x^2 - 2x = x(x-2)
11x - 22 = 11(x-2)
Since these both have the same value in the brackets, use 5at one of the brackets and the other is the combination of them together:
(x+11)(x-2)

Answer:
He should use the computer less.
Step-by-step explanation:
It is bad for mathews eyes.
with your formula, multiply the B by 2 and and it to the P multiplied by the height. Since they are all in feet, you do not have to convert.
24X2= 48+24X3 or 72 SA=120
