Answer:

The length is 20, and the width is 15.

Step-by-step explanation:

You have to write an expression to represent this situation. w can be the width, and the length can be 2w-10. To fnd the area, you multiply these together. w(2w-10) is 2w^2 -10w. From there, 15 is the only value of w that satisfies the equation, so w=15. Substitute 15 into your expression for lngth, and 2(15)-10 is 30-10 is 20, so the length is 20.

The whole thing has to equal 90 degrees. So the expression has to equal 40 degrees. The only number that satisfies the expression is 5. (5(5)+15)=40.

Factor −14 out of −12x−54y.
uysha [10]

we are given

-12x-54y

Since, we have to factor out -14

So, we will make both terms multiple of -14

so, we will multiply top and bottom of each terms by -14

-12x-54y=\frac{-14}{-14}\times -12x-\frac{-14}{-14}\times 54y

we can also write as

-12x-54y=-14\times \frac{-12x}{-14}-(-14)\times \frac{54y}{-14}

now, we can factor out -14

-12x-54y=-14\times (\frac{-12x}{-14}-\frac{54y}{-14})

now, we can simplify it

-12x-54y=-14\times (\frac{6x}{7}+\frac{27y}{7})..............Answer
