Answer:
Step-by-step explanation:
(a+b)^2=a^(2)+2ab+b^(2)
(a-b)^2=a^(2)-2ab+b^(2)
13)
(x+2)^(2)-(x-1)^2
x^(2)+4x+4-(x^(2)-2x+1)
x^(2)+4x+4-x^(2)+2x-1
6x+3
15)
(x+5)^(2)-(x+1)^2
x^(2)+10x+25-(x^(2)+2x+1)
x^(2)+10x+25-x^(2)-2x-1
8x+24
Answer:
slope: -3
y-intercept: 5
Step-by-step explanation:
y=mx+b, where m=slope and b=y-intercept
Answer:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-16-4*(x+4)-(4*x)=0
<u>Step 1:</u>
(-16 - 4 • (x + 4)) - 4x = 0
<u />
<u>Step 2: </u>
3.1 Pull out like factors :
-8x - 32 = -8 • (x + 4)
<u />
<u>Step 3:</u>
-8 • (x + 4) = 0
<u />
<u>Step 4:</u>
Solve : -8 = 0
This equation has no solution.
a non-zero constant never equals zero.
<u />
<u>Step 5:</u>
Solve : x+4 = 0
Subtract 4 from both sides of the equation: x = -4
<u>Step 6:</u>
x = negative 4 (-4)
