Answer:
13 cm, 39 cm, 39 cm
Step-by-step explanation:
If x is the short side, then the other two sides are 3x and 3x. The perimeter is the sum of side lengths:
x +3x +3x = 91
x = 91/7 = 13
3x = 3(13) = 39
The length of the short side is 13 cm; the other two sides are 39 cm.
To solve, we need to subtract from these two fractions. In order to do this, we will change one of them to have the same denominator as the other.
We have 5/14 and 1/7
Let us change 1/7
Multiply 2/2 (a form of 1 so it does not change the value of the fraction)
2/2 • 1/7 = 2/14
Now subtract from 5/14
5/14 - 2/14 = 3/14

Idk this answer because no triangles are shaded.
Answer:
= 5
Step-by-step explanation:
Substitute the given values into the formula
16 =
× 4(3 +
)
16 = 2(3 +
) ( divide both sides by 2 )
8 = 3 +
( subtract 3 from both sides )
5 =
