Answer:
x = -84
Step-by-step explanation:
(x/-7) - 2 = 10
Well you would do 1/2bh, 11 x 3 is 33 so half of that is 16.5
Use pythagoras teorem
10^2 = 3^2 + x^2
x^2 = 100 - 9 = 91
x = 9.54 feet to nearest hundredth
The common denominator for 3/8 and 1/3 is 24.
Reason: to get the common denominator you multiply the denominator of both
8*3= 24
