Answer:

(x+8)²

Step-by-step explanation:

x² + 16x + 64 = (x+8)²

(x+8)² = (x+8)(x+8) = x*x + x*8 + 8*x + 8*8 = x² + 8x + 8x + 64

         = x² + 16x + 64

Eliminating by multiplying <br> X+3y=1<br> -5x+4y=-24
gavmur [86]

Answer:

y = -1         x = 4

Step-by-step explanation:

(X+3y=1) 5            Multiply this equation by 5 to cancel out the x

-5x+4y=-24

-5x + 4y= -24

+ 5x + 15y = 5       Add both equations together

19y = -19                Divide both sides by 19

y = -1

Plug -1 for y into one of the equations

x + 3(-1) = 1             Multiply 3(-1)

x - 3 = 1

 + 3 + 3                  Add 3 to both sides

x = 4

F(x) = 2x2 - 5<br> and<br> g(x) = 5x + 7<br> Find<br> f(g(x)) = [ ? ]x2 + [ ]x +
lbvjy [14]

Answer:10x^2 -18

Step-by-step explanation:since f(x) is becoming the new x then youd subtitute the equation into the x of the g(x) equation. which would be 5(2x^2 -5) +7 which is 10x^2 -25 +7.and you'd simplify from there.
