There will be 23 layers of brick, because 7500/321 = 23 with 117 leftover.
Let t represent "total price." Then 0.20t = $1600, and t = $1600/0.20 =
$8000 (answer)
3. A=bh/2
2A=bh
h=2A/b.
8. Dy-Cx=E
Dy=E+Cx
y=(E+Cx)/D
a) (x+6)^2-25
b) (-6, -25)
Step-by-step explanation:
Perfect square trinomial! If you have 12x, divide by two and get 6, so we have (x+6)^2+q. Then solve for q. You get q as -25.
For b, we just take the vertex from vertex form. We get x+6=0 so x=-6, and q = -25, so the answer is (-6, -25).
