Hello from MrBillDoesMath!

Answer:

m^2 + 11m - 11, which is the first choice


Discussion:

6m +  (m-2)(m+7) +3 =

6m  + (m^2 + 7m - 2m -14) + 3 =

(6m + 7m - 2m) + m^2 + (-14 + 3) =             combine similar terms

11m + m^2 -11 =

m^2 + 11m - 11


which is the first choice


Thank you,

MrB

In sunlight, a vertical stick has a height of 5 ft and casts a shadow 3 ft long at the same time that a nearby tree casts a shad
leva [86]
The tree is 25 feet tall. Given the height of the stick and the shadow it cast, the angle formed by the sun and the stick's height can be obtained by taking the Inverse Tangent of 3/5. This is equal to 30.93. This angle is equal to the angle formed by the sun and the tree's height. Using the tangent formula, Tan (30.93)=tree's shadow (15 ft)/ height of the tree, giving the answer 25 feet.
