(6x-54)/3 = 22
Step-by-step explanation:
First I multiplied each side by 6.
6x=120
Then I subtracted 54 from each side.
6x-54=66
Finally, I divided each side by 3.
(6x-54)/3 = 22
I tried to make it look fancy.
Ответ:
where area is given
336=1/2*48*h
h =336*2/48
h=14 cm
now b=48 cm,h=14 cm
so by phythgorean theorm
(hy)^2=(base)^2+(h)^2
hy= √(196+2304)
Hypotenuse=50cm
