Answer:
2b^2
Step-by-step explanation:
according to the question equation is
(a^2 + b^2 ) - (a^2 - b^2)
a^2 + b^2 - a^2 + b^2
plus a square and minus a square gets cancel
b^2 + b^2
since they are like terms they can be added
2b^2
First solve the volume of the rectangular prism
V = l x w x h
where l is the length
w is the width
h is the height
V = 7 x 4 x 2.5
v = 70 cu cm
then solve the volume of the box
v = e^3
v = 0.5^3
v = 0.125
number of cubes = 70 / 0.125
number of cubes = 560 cubes
Answer:
y= 2/3x+3
Step-by-step explanation:
to be parallel they must have the same slope (2/3)
use the ordered pair to get the y-intercept (3)
A=2 and B=4...... because 2^2 and 3•4
30 minutes for each girl. 30min x 4girls = 120min for all girls. 120/60=2 hrs
