Step 1
find the a<span>rea of the first cross section

area1=b1*h/2
b1=8 m
h=10 m
area1=6*10/2------> 30 m</span>²

step 2
find the area of the second cross section

area 2=b2*h/2
b2=12 m
h=10 m
area1=12*10/2------> 60 m²

step 3
 find <span>the difference in the areas of the cross sections
</span>difference=60-30------> 30 m²

the answer is
30 m²

Solve for x. 3(x + 2) + 4(x - 5) = 10 x = 36/7 x = 24/7 x = 16/7 x = 9/7
IRISSAK [1]

3(x + 2) + 4(x - 5) = 10

Use the distributive property:

3x + 6 + 4x - 20 = 10

Combine like terms:

7x -14 = 10

Add 14 to both sides:

7x = 24

Divide both sides by 7:

x = 24/7

Pls help solve question 3
Lelu [443]

Answer:

If m is the midpoint of ab it means am is equal to mb

am = 3x + 8 and mb = 6x-4

and ab  = am + mb

first find the value of x by using am = mb

3x + 8 = 6x - 4

8 + 4 = 6x - 3x

12 = 3x

x = 4

ab = 3 (4) + 8

= 12 + 8 = 20 = mb

ab = am + mb

= 20 + 20

40

so, the value of ab is 40
