Answer:

Step-by-step explanation:

Given

Length of the base of the rectangular box $= 2x +5$

Width of the base of the rectangular box $= x$

Area of the base of the rectangular box

$= (2x + 5)(x)\\= 2x^2 + 5x$

a) Given

Area of the base of the rectangular box $= 58$ square centimeter

It can also be written as

$2x^2 + 5x = 58\\2x^2 + 5x - 58 = 0$

b) See the attached image

c) Volume

Base Area * height

$58 * (x-2)$

$x = -1.25 + \frac{22.11}{4} \\x = 4.27$

Volume $= 58 * 4.27 = 248.09$ cubic centimeter

Question 78 find the value of x

gladu [14]

For this case we have that by definition, the volume of a parallelepiped is given by:

$V = l * w * h$

Where:

l: It's the long

w: It is the width

h: It's the height

From the figure we have the following data:

$V = 975 \ ft ^ 3\\h = 9 \ ft\\w = 4ft\\x =?$

We must find the value of the length of the parallelepiped:

$975 = x * 4 * 9\\975 = 36x\\x = \frac {975} {36}\\x = 27.083$

Answer:

$x = 27.1 \ ft$

A ball is thrown into the air. The height h, in feet, of the ball after x seconds is given by the function h = −16(x − 2)2 + 72.

Anon25 [30]

Answer:

A. -16x²+64x+8

B. 72 ft.

Step-by-step explanation: A. Expand the perfect square binomial -16(x²-4x+4)+72, dist. -16 (-16x²+64x-64+72), then combine like terms (-16x²+64x+8)

B. Find the abs. max. by looking back at the vertex form. The max is (2,72). Use the y-value for the height.

Factor the expression using the GCF.

ss7ja [257]

Answer:

= 3 (3x + 5y)

Step-by-step explanation:

First find the GCF of 9 and 15 which would be 3. Then the GCF which is 3 is placed on the left of the parentheses. then you plug in the numbers. So 9x divided by 3 is 3x, and 15y divided by 3 is 5y.
