Answer:
(300*80) + (300*9) + (20*80) + (20*9) + (5*80) + (5*9) = 28925
Step-by-step explanation:
Given;
325 x 89
Expand 325 = 300 + 20 + 5
Expend 89.0 = 80 + 9
now multiple to two expanded numbers;
(300 + 20 + 5) x (80 + 9)
distribute the number accordingly as follows;
(300*80) + (300*9) + (20*80) + (20*9) + (5*80) + (5*9), now we have Six multiplication problems.
= 24,000 + 2700 + 1600 + 180 + 400 + 45
= 28925
The ordered pair that is the solution to these equations is (-2,-1)
work:
2(-2)+5(-1)=-9
3(-2)-4(-1)=-2
Step-by-step explanation:
(a) What is the area of the base of the box? Use appropriate units.
A=lw
A=8(4)
A=32 inches
(b) What is the volume of the box? Use appropriate units. How can
you use your answer to part (a) to determine the volume?
V=lwh
V=8(4)(5)
V=160 inches
