2(3 – 4a) + 5(a – 7)

Distribute 2  and 5 inside the parenthesis

Step 1:  2*3 - 2*4a + 5*a - 5*7

When we multiply it we will get

Step 2: 6 - 8a + 5a -35

Now we combine like terms. The terms that as same variables are like terms

-8a + 5a  is -3a

6 - 35 is -29

6 - 8a + 5a -35

Step 3: -3a -29

Final answer is -3a-29

omeli [17]

Answer:

The area of one trapezoidal face of the figure is 2 square inches

Step-by-step explanation:

<u><em>The complete question is</em></u>

The point of a square pyramid is cut off, making each lateral face of the pyramid a trapezoid with the dimensions shown. What is the area of one trapezoidal face of the figure?

we know that

The area of a trapezoid is given by the formula

A=\frac{1}{2}(b_1+b_2)h

where

b_1 and b-2 are the parallel sides

h is the height of the trapezoid (perpendicular distance between the parallel sides)

we have

h=1\ in\\b_1=1\ in\\b_2=3\ in

substitute the given values in the formula

A=\frac{1}{2}(1+3)(1)

A=2\ in^2
