The smaller triangle is 1/6 the size of the large one ( 5/30 = 1/

Area is squared 1/6 ^2 = 1/36

Multiply the area of the large triangle by 1/36:

270 x 1/36 = 270 /36 = 7.5

The area is 7.5 cm^2

The answer is A.

Answer:

  • (-4)³ = -64
  • -64

Step-by-step explanation:

The first step in solving the equation is to cube both sides:

  (∛x)³ = (-4)³ . . . . . = (-4)(-4)(-4) = 16(-4) = -64

  x = -64 . . . . . simplified

__

We're not sure what "checking" is supposed to involve here. Usually, one would check the answer by seeing if a true statement is made when the answer is put into the original equation.

  ∛(-64) = -4 . . . true

Many calculators will not compute √(-64) because they compute roots using logarithms. The log of a negative number is not defined.

So, the way one would check this is to cube both sides, which is how we got the answer in the first place. We expect the same result from doing the same operation again, so it isn't really a check.

What is the answer of this problem 8 (s+3)=72
Elden [556K]
First, distribute 8

8s+24=72

Now, isolate the variable with inverse operations

subtract 24 from both sides

8s=48

Divide by 8 on both sides

s=6
