Answer:

Option D is correct answer.

Step-by-step explanation:

For the area of Trapezoid we apply The formula

$\frac{1}{2}$ sum of parallel sides X distance between them

Here in the question we have area = 98 square units

parallel sides are 20 units and 8 units ,Plugging them in the above formula

Let d be the distance between them

98= $\frac{1}{2}$ [ 8+20] X d

98=14 X d

d= $\frac{98}{14}$

d = 7 units

Answer:

x = 7 units

Step-by-step explanation:

The area of the trapezoid is

A = 1/2 (b1+b2) *h

where b1 and b2 are the top and bottom and h is the height

Substituting what we know

98 =1/2 (20 +8) *x

Combine like terms

98 = 1/2 (28)x

98 = 14x

Divide by 14 on each side

98/14 = 14x/14

7 =x

The difference of six times a number and seven results in 35.

Answer is A. add 7, and then divide by 6. Your equation would be 6x-7= 35, so first you add 7 to both sides. 6x=42, and then divide by 6. x= 7

Solve the equation 2p/3-12=-2

-BARSIC- [3]

Hey there!

$\frac{2p}{3} - 12 = -2$

Firstly, we are going add $12$ on each of the sides that we're working with. like ↓

$p - 12 + 12 \\ \\ = -2 + 12$

This gives us $\frac{2}{3}p = 10$ (if you are wondering how we got the out come of $10$ it is because I added $-2 + 12 = 10$

Now multiply $\frac{3}{2}$ on each of your sides

$\frac{3}{2} ( \frac{2}{3}p) \\ \\ = \frac{3}{2} (10)$

Cancel the first set and you will find the value of $p$

$p = 15$

Good luck on your assignment and enjoy your day
