We are asked in the problem to determine the value of x in the equation <span>4x² + 2x = 7 using completing the square method. in this case,

</span><span>4x² + 2x = 7
x2 + 0.5 = 1.75
(x + 0.25)^2 - 0.0625 = 1.75
</span>(x + 0.25)^2 = 1.8125
<span>x+0.25=1.3462
</span>x1 =1.0963
x2 =-1.5962

PLEASE HELP ASAP DUE IN 3 MINUTES

Inga [223]

Answer:

<u>1728 in²</u>

Step-by-step explanation:

For the area of B, you need to find the length and width (height and base, whatever you want to call it).

For the height, you would need to do: 144 - 36 - 24 - 36 = <u>48 inches</u>

For the base, you would need to do: 60 - 24 = <u>36 inches</u>

Now you multiply the base and height to get the area: 48 x 36 = <u>1728 in²</u>

For each value of y, determine whether it is a solution to 12 = 2y +8.<br> Is it a solution

grin007 [14]

Answer: 2(0) + 8 does not equal 12, not a solution.

2(2) +8 = 12 yes it is a solution

2(-3) + 8 does not equal 12, not a solution

2(5) + 8 does not equal 12, not a solution.

Step-by-step explanation:

Looks like you need to plug in each y value given and multiplied by 2 and add 8

2(0) + 8 does not equal 12, not a solution.

2(2) +8 = 12 yes it is a solution

2(-3) + 8 does not equal 12, not a solution

2(5) + 8 does not equal 12, not a solution.

Again, please help. i dont know any of this

Levart [38]

$\textrm {Cylinder volume :}$

$\mathrm {Volume = \pi r^{2}{h}}$

$\mathrm {Volume = 3.14 \times (\frac{4}{2})^{2} \times 3}$

$\mathrm {Volume = 3.14 \times 12}$

$\mathrm {Volume = 37.68cm^{3}}$

$\textrm {Rectangular prism volume :}$

$\mathrm {Volume = length \times width \times height}$

$\mathrm {Volume = 6 \times 5 \times 7}$

$\mathrm {Volume = 30 \times 7}$

$\mathrm {Volume = 210cm^{3}}$

$\textrm {Total volume of composite figure :}$

$\textrm {Volume of cylinder + volume of rectangular prism}$

$\mathrm {37.68 + 210}$

$\mathrm {247.68cm^{3}}$
