Answer:
C. Use properties of equality to get the variable on one side of the equation and constant terms on the other.
Step-by-step explanation:
In solving an equation, It is true that properties of equality should be used by putting the variable on one side and the constant on the other side.
Now let use an example to drive this;
Given:
2x - 9 = x + 8
This is an equation, and what we have on both sides should be equal.
Collect like terms;
2x - x = 8 + 9
x = 17
So the solution is 17.
This is the best way to solve an equation.
V=LWH=20
L is 5 more than W
V=5+W
H is 1 less than W
H=-1+W
easy, sub 5+W for L and -1+W for H in LWH=V=20
20=(5+W)(W)(-1+W)
expand
20=W^3+4W^2-5W
minus 20 both sides
W^3+4W^2-5W-20=0
either factor or graph to find the possible values for W
(W+4)(W^2-5)=0
set each to zero
W+4=0
W=-4
impossible, measures cannot be negative
W^2-5=0
add 5
W^2=5
sqrt both sides
W=√5
sub back
L=5+W
L=5+√5
aprox
7.24 rounded
H=-1+W
H=-1+√5
aprox
1.24 rounded
the dimentions are
√5 by (5+√5) by (-1+√5) or aprox
2.24in by 7.24in by 1.24in
