Answer:
18
Step-by-step explanation:
a^2 + b^2 = c^2
in this case 24 is a and 30 is c
24^2 = 576
30^2 = 900
900 - 576 = 324
the square root of 324 is 18
Answer:
5
Step-by-step explanation:
move the terms 6x-4=16+2x
collect like terms 6x-2x=16+4
divide both sides 4x=20
x=5
Answer:
Day 1=0.075
Day 2=0.0375
Step-by-step explanation:
Divide each day by 2
It isn't because since 9 is the product of 3×3, you multiply the 6 by 3 as well, which makes 18.
Answer:
217 ft^2
Step-by-step explanation:
Area for triangle is 1/2 bh
The b is the base and h is the height
For the base, 4 is included but we need to find the other piece for the base. so…
8 + 9 = 11 + ?
17 = 11 + ?
? = 17 - 11
? = 6
Then add 6 and 4
10
so the base of the triangle is 10. now…
10 x 7 = 70/2 = 35
The area of the triangle is 35
Now the square
8 x 7 = 56
The area of the square is 56
Finally the rectangle
9 x 14 = 126
The area of the rectangle is 126
Now add the areas for all of the shapes
35 + 56 + 126 = 217 ft^2
The area of the figure is 217 ft^2
