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>

Answer:
384.12 cubic inches
Step-by-step explanation:
Length: 9 7/10 = 9.7 inches
Weight: 1 4/5 = 1 8/10 = 1.8 inches
Height: 22 inches
Volume of a rectangular prism: V = l*w*h
V = 9.7 * 1.8 * 22
V = 17.46 * 22
V = 384.12 cubic inches
Hope this helps!
Answer:
That’s correct
Step-by-step explanation:
y < 4 does mean that y is less than 4. if it helps. Wherever the open side is, means that one is greater. I always look at it like an alligator eating the bigger number
1298 - 4x =171 + 3x
Add 4x to both sides
1298 = 171 + 7x
Subtract 171 from both sides
1127 = 7x
Divide by 7 on both sides
x = 161
They will both say the number 161 at the same time.
