Which step shows the result of applying the subtraction property of equality?

Step 3.

Step-by-step explanation:

We have the equation,

Step 1: ..........Opened the brackets on the left side.

Step 2: 3x + 6 = 3..............Added the numbers on the left.

Step 3: 3x = -3...............Subtracted both sides by 6.

Step 4: x = -1....................Divided both sides by 3.

Thus, we can see that,

Step 3 shows the result of applying the subtraction property of equality.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
