x = -2
Step-by-step explanation:
Answer:
22
Step-by-step explanation:
(4 x 4) + (3 x 2) = 16 + 6 = 22
Answer:
528 cm²
Step-by-step explanation:
First I would calculate the area of the side rectangles:
20 x 9 = 180 cm²
There are two identical rectangles on both sides so i would x2
180 x 2 = 360 cm²
The area of the middle rectangle:
6 x 20 = 120 cm²
The area of the triangles:
Area of a triangle = (Base x Height)/2
8 x 6 = 48
48 ÷ 2 = 24
There are two identical triangles on the bottom and the top so x2
24 x 2 = 48
Now add all the values up:
360 + 120 + 48 = 528 cm²
I hope this helps!
The computation shows that the number of groups that can be made is 4 groups.
<h3>How to calculate the number?</h3>
From the information given, it should be noted that the number is said to be more than 30 and lower than 40.
In this case, it can be noted that the number that is more than 30 and lower than 40 and can be divided into 8 is 32.
Therefore, the number in each group will be:
= 32/8
= 4
