Substitute 0 in for x or y
8(0) ?? 4y=56
4y=56
Y= 14, x=0
8x ?? 4(0)=56
8x=56
X=7, y=0
Answer:
(4x +3)²
Step-by-step explanation:
The form of a perfect square trinomial is ...
(a +b)² = a² +2ab +b²
The factors are easily found as the square roots of the first and last terms.
16x² +24x +9
= (√(16x²) +√9)²
= (4x +3)²

The answer should be -3 you just subtract it
Answer:
The total would be $87.53
Step-by-step explanation:
Answer:
<u>Yes</u>
- (2 · x) + (2 · 7) = 36
- x + 7 = 18
- 2x + 14 = 36
<u>No</u>
- 2x + 7 = 36
- 2(x + 7) = 72
- x + 14 = 36
Step-by-step explanation:
It is appropriate to eliminate parentheses as a first step. This can be done using the distributive property, resulting in either of ...
- 2x +2·7 = 36
- 2x +14 = 36 . . . . . 2·7 evaluated mentally
or by dividing the equation by the factor outside parentheses, resulting in ...
___
Any of the equations other than these represent violations of the equal sign. Something has been done to one side of the equation without the same thing being done to the other side.
