V=(7*6)/2 *8 the third option
you multiply the height with the base of the triangle and you get the area of the base of the prism so you multiply it with the height of the prism to get the volume
Answer:
(x-7) (x+4)
Step-by-step explanation:
x^2 - 3x - 28
What two numbers multiply to -28 and add to -3
-7*4 = -28
-7+4 = -3
(x-7) (x+4)
Answer:
She has 24,50$ left
Step-by-step explanation:
3,50*5 = 17,50

Answer:
B
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
y + 10 + 2y + 50 = 180 , that is
3y + 60 = 180 ( subtract 60 from both sides )
3y = 120 ( divide both sides by 3 )
y = 40 → B
