11.) our question issss.....
7 x __ = 420
all we have to do here is the opposite. so lets divide 420 by 7 here the math
420/7 = 60
sooooo answer is 60
12.) our question issss....
50 x __ = 0
well always keep in mind anything we multiply by 0 is going to be zero
so for example if we did 4 x 0 is would equal 0 because there arent even any rows to begin with
so your answer issss 0!
have a good one :)
merry christmas:D
Let
x-------------> amount added <span>to each side
</span>A-------------> area increased----------> 84 ft²
we know that
A=(10+x)*(5+x)=84-----------> 10*5+10*x+5*x+x²
50+15x+x²=84----------> x²+15x-34=0
<span>solving the second order equation
</span>x1=-17
x2=2
the answer is x=2 ft
