A = 1/2 * b * h
A = 178.5
b = h + 4
178.5 = 1/2 * (h + 4) * h
357 = h^2 + 4h
h^2 + 4h - 357 = 0
(h - 17)(h + 21) = 0
h - 17 = 0
h = 17
h + 21 = 0
h = -21 .....not this one because it is negative
b = h + 4
b = 17 + 4
b = 21
so the height is 17 inches and the base is 21 inches <==
Answer:

Step-by-step explanation:
common sense
Answer:
48
Step-by-step explanation:
91+41+?=180
91+41=132
180-132=48
36, since they have no common factor the lcm of four and nine is four times nine
The discriminant of ff is given by:
b^2-4ac=24^2-4 (multiply)3(multiply)48=576-576=0
2
−4ac=24
2
−4⋅3⋅48=576−576=0.
How many real number zeros does ff have?
Since the discriminant of ff is \green{0}0, ff has 11 distinct real number zero. Therefore, the graph of ff touches the xx-axis once. The graph of ff is shown below
