First: Find x

I used the larger rectangle first but you can do either one.

I added (8x+5) + (8x+5) + (6x+7) + (6x+7) =360

I made the sides equal to 360 because a square’s interior angles are equivalent to 360 degrees.

(8x+5) + (8x+5) + (6x+7) + (6x+7) =360

28x+24 = 360

28x = 336

X = 12

Next: Implement 12 in for x in every equation and follow the formula for a rectangle’s area.

A = b*h

BIG SQUARE:

(8(12)+5) + (8(12)+5) + (6(12)+7) + (6(12)+7)

=360

LITTLE SQUARE:

2((2(12)+5) + (6(12)+7)) = 90

Lastly: Subtract the little squares area from the biggest square

360 - 90 = 270

Misha Larkins [42]
So first of all write down 82 / 12 and do the problem.Divide 82 / 12.

Next you get the answer which is,based on a calculator,which is <span>6.83333333333.

But because it's money well I'm guessing it could be 6.83 or 6.833 or the real answer.

The question is confusing but I hope I could help :D</span>

Help 0.06 is 10 times as much as
Ipatiy [6.2K]

Answer:

0.06 is 10 times as much as 0.006

Step-by-step explanation:

let the number be x

as per the condition 0.06 is 10 times as much as x.

Solve for x:

10 times as much as x represents as 10 \times x

Then;

0.06 = 10 \times x                 ......[1]

Division property of equality states that you divide the same number to both sides of an equation.

divide by 10 to both sides in equation [1];

\frac{0.06}{10} = \frac{10x}{x}

Simplify:

x = 0.006

Therefore, 0.06 is 10 times as much as 0.006
