Answer 1

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
