Answer:
72
Step-by-step explanation:
2.5*4=10
10*2=20
4*4=16
16*2=32
2.5*4=10
10*2=20
20+20+32=72
Answer:Volume
Quantity of three-dimensional space
Step-by-step explanation:
Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface. For example, the space that a substance (solid, liquid, gas, or plasma) or 3D shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre
5^-2 = .04
5^5 = 3125
.04 x 3125 x 5 = 625
Answer:
15d^2 +7d-4
Step-by-step explanation:
(5d+4)(3d-1)
FOIL
first 5d*3d = 15d^2
outer 5d(-1) = -5d
inner 4*3d = 12d
last 4*-1 = -4
Add together
15d^2 -5d+12d -4
15d^2 +7d-4
If you use metric conversion (shown below), you will find that 9 meters = 90 cm. Tell me if you need further explanation.
