Answer:
56cm^3
Step-by-step explanation:
Split the shape into a triangle and a rectangle
Area of triangle = half base X height
=half of 4X(6-2=4)=8 8X2=16
The volume of the triangle is 16
4X5X2=40 40+16=56
Answer:
B)
Step-by-step explanation:
(a-4)²-a-4
a²-8a+16-a-4
a²-9a+12
D & C are the correct answers.This is because of the Distributive Property.
y+y+y +3z = 3y + 3z.
3(y+z) also gives you 3y + 3z.
C is correct because everything adds up to 3y +3z:
2y+2z+y+z = 3y +3z
Answer:
D
Step-by-step explanation:
You do 180-125 to find the angle (because its a straight line) and then you get 55, then you have a right angle so you have 90 and then you do:
55+90+p=180
and then you get
145 +p=180
180-145=35
p=35
P = 2L + 2w
Subtract 2L
from each side: P - 2L = 2w
Divide each side
by 2 : (P - 2L) / 2 = w
You could also write it as (P/2 - L) = w
Both answers are the same.
