Base of triangle exceeds the height by 4. If the area is 178.5 square inches, find the length of the base and the height of the
xxMikexx [17]
Area of a triangle:
A= (1/2)(bh)

In this problem we are given:
A= 178.5 in^{2}
b= h+4 in
h= UNKNOWN ("h")

Plug in our values into the area equation and solve for "h":
A= \frac{1}{2} bh
178.5 = \frac{1}{2} ((h+4)h) (multiply each side by 2 to get rid of the 1/2)
357 =  ((h+4)h)
357 =  h^{2} +4h
0=  h^{2} +4h -357
(357/21=17)
0= (h+21)(h-17) (solve both inequalities separately)

0= (h+21)
-21= h ( a negative height is not possible so, this answer is incorrect.)

0=(h-17)
h=17 in

Answer: base = (h+4)= (17+ 4) b= 21 in h= 17in

Twice the sum of a number and seven is three times the number.
Trava [24]
The equation will be 2x + 7 = 3x

subtract 2x from bothsides, you get 7 = x

so x is equal to 7 

EDITED

sorry, i didnt read the sum part, so my answer is considered wrong ahaha

2(x+7) equals 3x

distribute, you get 2x+14=3x

then subtract 2x,

the answer for x is 14
