8 0

Answer:

176 units

Step-by-step explanation:

All sides of this octagon are of the same length. Thus, x + 7 = (4/3)x - 1/3.

Mult. all terms by 3 will remove the fractions: 3x + 21 = 4x - 1.

Then 22 = x. The perimeter of this figure is 8(22), or 176 units.

Find the missing variable for a parallelogram: A = 28in2 h = b = 6.3 in (1in=2.54cm)

aivan3 [116]

The formula of an area of parallelogram:

$A=bh$

We have

$b=6.3\ in$ and $A=28\ in^2$

Substitute:

$6.3h=28$ divide both sides by 6.3

$h=\dfrac{28}{6.3}\\\\h=\dfrac{280}{63}\\\\h=4\dfrac{28}{63}\\\\h=4\dfrac{28:7}{63:7}\\\\h=4\dfrac{4}{9}$

Answer: $h=4\dfrac{4}{9}\ in$
