Start off by knowing that the two triangle are congruent. By knowing this you can turn the given numbers into fractions.
9/72 = 7/7x+7
then cross multiply, which equals
63x + 63 = 504
then solve this equation
63x = 441 - subtract 63 from both sides
x = 7 - divide by 63 from both sides
so your answer is x=7
The Formula Of Volume Is :
V = L*W*H. So, Lets Plug In The Known Values.
V = 16*16*16.
16*16 = 256.
256 * 16 = 4096 yr^3. This Is The Volume. Any Further Questions?
Solution
-3b + 11 = -18 + 8b
-3b - 8b = -18 - 11
-11b = -29
b = 29/11
Slope is -4-1/-7-3= -5/-10=1/2 it is y2-y1/x2-x1
the equation is y-y1= m(x-x1)= y-(-4) =1/2(x-3) =y+4 =1/2(x-3)
