Answer:
the answer is 17 since you multiply a negative 5 by a negative which is positive 10 and add 7 to that its 17
Step-by-step explanation:
Here is the answer OwO:
A 12-foot flagpole casts a nine-foot shadow. The measure from the top of the shadow to the top of the flag pole is 15.
Here is the explanation/work OwO:
<u><em>Switch sides.</em></u>
c^2=12^2+9^2
<u><em>12^2=144</em></u>
c^2=144+9^2
<u><em>9^2=81</em></u>
c^2=144+81
<u><em>Add the numbers: 144 + 81 = 225</em></u>
c^2=225
<u><em>For x^2 = f(a) the solution is √f(a)</em></u>
c = 15
Therefore, your answer will be 15.

Answer:
y = 6.5
Step-by-step explanation:
When triangles are similar, we can set up a proportion to compare the sides. I will have the "left" side on the bottom of the fractions, and the side I am solving for on the top.

[Cross multiply]
12y = 78
y = 6.5
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.

Your surface area is: S=x^2+4xh=84 square inches and h=2 inches; so you get:
x^2+(4×2)x=84
x^2+8x-84=0 qhich is a quadratic equation. Using the quadratic formula you get two results for x:
x1=-14 and x2=6
choose the second (positive)
