To solve this problem you must apply the proccedure shown below:

1. If the first octagon and the second octagon are similar, you need to find the ratio of the lengths, as below:

ratio=21.8in/10.9in\\ ratio=2

2. The ratio of the area is:

ratio=2^{2} =4

4. Then, you must multiply the ratio by the area of the first octagon to calculate the second area:

A2=4A1\\ A2=4(573.67in)\\ A2=2294.68in^{2}

The answer is: 2294.68in^{2}

What is the answer to this equation? Algebra 1 . |10-6r| -3 = 13 ??
LUCKY_DIMON [66]

Answer:

r = -1 or r = 13/3

Step-by-step explanation:

Solve for r over the real numbers:

abs(10 - 6 r) = 16

Split the equation into two possible cases:

10 - 6 r = 16 or 10 - 6 r = -16

Subtract 10 from both sides:

-6 r = 6 or 10 - 6 r = -16

Divide both sides by -6:

r = -1 or 10 - 6 r = -16

Subtract 10 from both sides:

r = -1 or -6 r = -26

Divide both sides by -6:

Answer: r = -1 or r = 13/3

VERY EASY WILL GIVE BRAINLEST THANK YOU AND FRIEND YOU Determine whenter (18+35)x4= 18+35x4 is true or false. Explain.
Ray Of Light [21]

Answer:

False because on the left side of the equation you are adding 18 and 35 first and on the right you are multiplying 35 and 4 first. This will give you an unequal equation when solved.

Let's solve each side

(18+35)*4=212

but 18+(35*4)=158
