Answer:

15x -45
3(5x -15)

Step-by-step explanation:

The expression can be fully factored as ...

3·5·(x-3)

Equivalent expressions can be formed by eliminating parentheses to give ...

15x -45

or by combining different pairs of factors:

3(5x -15)
5(3x -9)

Of course any of the terms can be broken apart and/or combined in different ways:

= 15(x -2) -15

= (7x -7) + 2(4x -19)

Isolate the w. Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS. First, multiply 4/3 to both sides

(3/4)(4/3)(8w - 12) = 3(4/3)

8w - 12 = (12/3)

8w - 12 = 4

Isolate the w. Add 12 to both sides

8w -12 (+12) = 4 (+12)

8w = 4 + 12

8w = 16

Finally, to completely isolate the w, divide 8 from both sides

8w/8 = 16/8

w = 16/8

w = 2

2 is your answer for w

hope this helps

Find the area of the trapezoid.

anzhelika [568]

Answer:

488 sq ft

Step-by-step explanation:

Alright, so:

The formula for the area of a trapezoid is as follows:

$A=\frac{a+b}{2} h$

In this case, a and b are the bases.

Insert the values into our equation and we have...

$A = \frac{39+17}{2} (16)\\A = \frac{56}{2} (16)\\A = 488ft^{2}$
