The last one are like terms because they can combine.
63miles/1hr = 1071miles/ h hours
Cross multiply
1071= 63h, divide both side by 63
h = 17

The formula A=1/2bh is used to find the area of a triangle. You can find from the diagram that the base of this triangle is 9cm, and the height is 4cm. Plug those numbers into the area of a triangle formula.
A=1/2(9)(4)
Multiply to get 18 square cm, which is choice D.
Answer:
x^2 + 7x + 3 in^2.
Step-by-step explanation:
The area of the whole frame = (5x + 3)(x + 6)
= 5x^2 + 33x + 18
So the area of the rim = 5x^2 + 33x + 18 - (4x^2 + 26x + 15)
= x^2 + 7x + 3 in^2.
