Answer:
x = 4.5
Step-by-step explanation:
6x+7=4x+4y
The first step is to simplify the equation by combining the x terms
Subtract 4x from each side
6x-4x +7 = 4x-4x+4y
2x+7 = 4y
We know the y value is 4
Substitute y=4 into the equation
2x+7 = 4(4)
2x+7 =16
Subtract 7 from each side
2x+7-7 =16-7
2x=9
Divide by 2
2x/2 =9/2
x= 4.5
Answer:
Step-by-step explanation:
basically, what they are asking you is to factor and then plug in the values (x=3; x=4) that they gave you.
first, you need to factor out the equation.
start with the original equation.
V=4x^3+10x^2+4x
factored form:
V= 2x(2x^2+5x+2)
next, you're going to want to plug in the values.
the answer asks for x=4, but you should do both.
v=2(3)(2(3)^2+5(3)+2)
do not forget to do the exponents before!
v=6(18+15+2)
v=6(35)
v=210 ft^2
that's the answer for if x was equal to 3.
V= 2x(2x^2+5x+2)
<em>don't forget to write the original equation first. </em>
V=2(4)(2(4)^2+5(4)+2)
<em>V=8(36+20+2)</em>
<h2>
<u><em>V=464 ft^2 </em></u></h2>
⬆is your answer! hope this helped!!
Answer:
Step-by-step explanation:
So the first 1 on the left is A=2lw+2lh+2wh
Then the first 1 on the right the property you use is distribute
Then the rest I don’t know I’m sorry
