Answer:volume is lengthxwidthxheight
Step-by-step explanation:
Length=3
Width=7
Height=10
3x7x10=210 inches ^3
The answer is C. Because the side triangles inner corner is 51 so the inner corner of the big train fled are 129. 129 + 20 equals 149 and 180 - 149 equals 31.
I think its x^2(18x^2 -9+4x) sorry if I’m wrong
we know that
the car gets 18 miles per -----------> 1 gallon of gasoline
so
for 543 miles ---------------------> x gallons of gasoline
by proportion
543/18=x/1---------->x=543/18------->x=30.17 gallons
therefore
the answer is
30.17 gallons
X = -1 11x+6=6x+1 which leads to 5x=-5
