For this standard for, a = -1, b = 0 and c = 18.
In order to find this, you must first multiply the two parenthesis by each other.
(5 + x)(5 - x)
25 + 5x - 5x - x^2
25 - x^2
Now we need to set it equal to the other side and solve for 0.
25 - x^2 = 7 ----> subtract 7 from both sides.
18 - x^2 = 0 -----> now readjust the order
-x^2 + 18 = 0
So, once we've reached here, the a value is always the coefficient of the x^2 term (-1), b is the value of the coefficient of the x term (0) and c is the constant (18).

Answer:
see below
Step-by-step explanation:
OK, so volume of LxWxH. so for shape 1 it's 14x8x7=784
Its asking for base times height which is 112 so the blanks are 112 then 7 then 784
the second one is the same. the base is 81 times the height of 9 which is 729
so the blanks are 81 than 9 than 729
the third base is 20 times height of 11 which is 220
so the blanks are 20 than 11 than 220

Answer:
0.02(750)+0.03(x−750)=37.5
Step-by-step explanation:
Given data
Melissa earns a 2% commission on the first $750 of sales
= 0.02(750)
She earns a 3% commission on the amount of her sales that are greater than $750 each week
let the amount of her sales be x
= 0.03(750-x)
Melissa earned $37.50 in commissions last week.
= $37.5
Her total earnings is $37.5
37.5= 0.02(750)+ 0.03(x-750)
37.5= 15+0.03x- 22.5
37.5-15+22.5= 0.03x
45= 0.03x
x= 45/0.03
x= 1500
