Answer:
A. 4(x^2 + 2x + 1) + 15 - 4 = 0
Step-by-step explanation:
Because we have to make the expression in the brackets a perfect square by adding 1 and then, as we have introduce + 1 * 4 = + 4 into the equation, we must later subtract the 4.
Answer:
6x + 10t
Step-by-step explanation:
We know that each cheese pizza (c) is $6, and each four topping pizza (f) is $10.
Knowing this, the total of all the pizzas is going to be 6* the amount of cheese (c) plus 10* the amount of four-toppings.
6x + 10t
Answer:
solution for -4 + 3y = 23
3y = 23+4
3y = 27
y = 9
solution for X - y = -7
X = 1
y = 8
B. 50$
C. y=25x+50
D.550$
Explanation:
D. y=25(20)+50
=500+50
y=550$
