X^2 - 10x + 8 =0
x^2 - 10 + (-10/2)^2 - (-10/2)^2 + 8 = 0
(x - 5)^2 - 25 + 8 = 0
(x - 5)^2 - 17 = 0
To be honest , this is the final step for this equation. It seems like there is no any suitable answer for this question..
To me , I think the best answer will be the third option.
x - 5 =0
x = 5
2x-10 = 0
2x = 10
x = 5
I guess this answer seems like legit.. So I will choose the third option.
Answer:
4. 11/6, 121/36
5. 5/8, 25/64
6. 4/7, 16/49
7. 14/9, 196/81
Step-by-step explanation:
The ratio of perimeters is the same as the ratio of corresponding legs:
perimeter ratio = red leg/blue leg
The area ratio is the square of that:
area ratio = (perimeter ratio)²
__
<h3>4.</h3>
perimeter ratio = 11/6
area ratio = (11/6)² = 121/36
__
<h3>5.</h3>
perimeter ratio = 5/8
area ratio = (5/8)² = 25/64
__
<h3>6.</h3>
perimeter ratio = 4/7
area ratio = (4/7)² = 16/49
__
<h3>7.</h3>
perimeter ratio = 14/9
area ratio = (14/9)² = 196/81
H = 30.25 hours
c = 15(30.25) = 453.75
c = 453.75 + 245
c = 698.75
