Answer:
20
Step-by-step explanation:
- x+20%=24
- x+x*20/100=24
- x+0.2x=24
- 1.2x=24
- x=24/1.2
- x=20
A (15.4-8.1=7.3) has two significant figure so A is the ANSWER
while the all other options has 3 significant figure
answer is C. 252 ft^2
split the figure into two pieces and first figure out the rectangle (shown in turquoise).
If you multiply the width and length (18*6) you should get 108.
Then figure out the trapezoid (in magenta). the formula is (a+b)/2*h where a and b are the bases and h is the height. the bases are given, 6 and 18. to find the height, subtract the entire figure's height by 6, which is 18-6 and gives us 12. so the formula converted to this problem is (6+18)/2*12. simplify parenthesis and get 24/2*12. 24/2=12, so multiply 12*12. The area of the trapezoid is 144. Add the areas of both figures together and get 252.

Answer:
5/8, -5/8
Step-by-step explanation:
64x^2 = 25
divide both sides by 64
x^2 = 25/64
take the square root of both sides, and the negative square roots
