I believe it's 14 if you find the difference between the largest and smallest number
Answer: option a
Step-by-step explanation:
You must apply the formula for calculate the surface area of the prism, which is shown below:
Where:
b=8 cm
h=3 cm
l=10 cm
s=5 cm
When you susbstitute the values shown above into the formula for calculate the surface area, therefore you obtain:
Answer:
D and E
Step-by-step explanation:
remote interior angles are not adjacent to a given angle. or basically 1 is our exterior angle, so the opposites of 1 and the remote interior angle.
DE + EF = 4x+2
DE = x+7
EF = 7
Substitute these in
x + 7 + 7 = 4x + 2
x + 14 = 4x + 2
subtract x from both sides
14 = 3x + 2
subtract 2 from both sides
3x = 12
divide both sides by 3
x = 4
substitute this in to find the length of DE
DE = x + 7
(4) + 7 = 11
the answer is 11
