Answer: 51.4275 or 51.428571 (repeating decimals) feet

Step-by-step explanation:

P = perimeter

L = length

W = width

Represent W as  \frac{3}{4} L

Find L

P = 2L + 2W

240 = 2L + 2(\frac{3}{4}L)

240 = 2L + \frac{3}{2} L  or you can write 3/2 as 1.5

240 = 2L + 1.5L

240 = 3.5L

\frac{240}{3.5} L = \frac{3.5L}{3.5}

L =  ≈ 68.57 or 68.571428 (but this is <em>repeating decimals</em> so I rounded it)

Find W

\frac{3}{4} L

\frac{3}{4}  * 68.57 = 51.4275

Or if you want unrounded version 51.428571 (repeating decimals)

Because a ║b you can say: 
-60 -2x = -70 -4x ⇒ -2x + 4x = -70 + 60 ⇒ 2x = -10 ⇒ x = -5 :)))

Solve and explain how you did​
Sliva [168]

Answer:

We conclude that:

  • -\left(9x\right)^0=-1

Step-by-step explanation:

Given:

-\left(9x\right)^0

To determine:

Explain how to solve the expression

<u>Solving the expression</u>

-\left(9x\right)^0

Apply the exponent rule

a^0=1,\:\quad \:a\ne \:0

so the expression becomes

-\left(9x\right)^0\:=\:-1

Therefore, we conclude that:

  • -\left(9x\right)^0=-1

BRAINIEST FOR CORRECT ANSWER!! :))) ——————-

Answer:
3 < c < 13
Step-by-step explanation:
A triangle is known to have 3 sides: Side a, Side b and Side c.
For a triangle, one of the three sides is longer than the other two sides. (The only exception is when we are told specifically that a triangle is an equilateral triangle, where all the 3 sides are equal to each other).
To solve the above question, we would be using the Triangle Inequality Theorem.
The Triangle Inequality Theorem states that the summation or addition of the lengths of any two sides of a triangle is greater than the length of the third side.
Side a + Side b > Side c
Side a + Side c > Side b
Side b + Side c > Side a
For the above question, we have 2 possible side lengths for the third side of the triangle. We are given in the above question,
side (a) = 5
side (b) = 8
Let's represent the third side as c
To solve for the above question,we would be having the following Inequality.
= b - a < c < b + a
= 8 - 5 < c < 8 + 5
= 3 < c < 13
