It is given in the question that B is in between C and D.

Therefore

$CB+ BD = CD$

Substituting the given values of CB,BD and CD, we will get

$4x-9+3x+5=17$

Combining like terms, we will get

$7x-4=17$

Now we need to move 4 to the right side by adding 4 to both sides, that is

$7x = 21
\\
x=3$

9 tables

Step-by-step explanation:

First, subtract the remainder from the original:

98 - 26
72

Now, we know that she places 8 spoons per table, so let's divide the number of spoons by 8 to find the number of tables:

72 ÷ 8
9

A trapezoid with a right angle and an area greater than 40 square inches

andreev551 [17]

Answer:

see the attached figure.

Step-by-step explanation:

We need to draw a trapezoid with a right angle and an area greater than 40 square inches

See the attached figure

The area of the trapezoid = 0.5 ( base_1 + base_2 ) * height

So, as shown ABCD is a trapezoid with a right angle at A

base_1 = 14 inches , base_2 = 10 inches and the height = 5 inches

So, the area = 0.5 ( 14 + 10 ) * 5 = 0.5 * 24 * 5 = 60 square inches > 40

Note: we can use any numbers other than 5 , 10 , 14

for example: 5 , 8 , 12 in this case the area = 0.5 * (8+12) * 5 = 50 > 40

<u>The point is choose any numbers which gives area > 40</u>
