Answer:
m = j + 10
m + 3 = 3x
Step-by-step explanation:
Activity 3
1) 2m^2(4m^2 + 3m + 2)
2) (x + 4)^2 (x - 4)
3) (x + 9)(x - 7)
4) 5y(17y - 4z)
5) (2x - y)(6x + 5y)
Activity 4
1) 80 units because when you sub h = 9, you get 400 as the answer and because it’s a square, you square root 400 which is 20 units per side.
2) x = 7cm because when you multiply (x + 5)(x - 3), you get x^2 + 2x - 15 = 48 and when you solve it you get x is equal to 7, -9, because the length of the rectangle is positive x is equal to 7.
3) the binomial would be (9x + 1)^2.
Answer:
288 units^3
Step-by-step explanation:
To find the volume of this prism, first find the area of the triangular end.
A = (1/2)(base)(height) comes out to A = (1/2)(6)(8), or A = 24 square units.
Next, multiply this area by the length of the prism: V = (24 units^2)(12 units) = 288 units^3
The volume is 288 units^3
