Answer:
Hey
Step-by-step explanation:
I bevlive your answer is B. If you multiply the two numbers you get 1.4
Answer:
Step-by-step explanation:
<u>Area formula:</u>
<u>The height is:</u>
- h = (x + 2)sin 45° = √2(x + 2)/2
<u>Substitute the area value an set an equation:</u>
- 4√2 = (2x - 3)√2(x + 2)/2
- (2x - 3)(x + 2) = 8
- 2x² + x - 6 = 8
- 2x² + x - 14 = 0
- D = 1 + 4*2*14 = 113
- x = (-1 + √113)/4 = 2.41 (rounded)
Note. the second root ignored as negative
It helps you multiply by two by giving you the answer to the expression.
Example: 2•5=10/
60/500=?/100
60/5=12
12/100
12%.
