The combined area of the 3 windowpanes and frame shown below is 924 in.2. The frame is of uniform width. What is the side length

wariber [46]

Answer:

Option A. $x=10\ in$

Step-by-step explanation:

we know that

The combined area of the 3 windowpanes and frame is equal to

$(3x+12)(x+12)=924\\ \\3x^{2}+36x+ 12x+144=924\\ \\ 3x^{2}+48x-780=0$

using a graphing tool to solve the quadratic equation

The solution is $x=10\ in$

What is (2+y)³ written out? 8 + 12y + 6y² + y³ 6 + 8y + 4y² + y³

AveGali [126]

$\boxed{(2+y)^3-cube\ the\ sum\ of\ the\ numbers\ 2\ and\ y}$

$Use:\ (a+b)^3=(a+b)(a+b)(a+b)=a^3+3a^2b+3ab^2+b^3\\----------------------------\\(2+y)^3=2^3+3\cdot2^2\cdot y+3\cdot2\cdot y^2+y^3=8+3\cdot4y+6y^2+y^3\\\\=8+12y+6y^2+y^3\\========================================$

$8+12y+6y^2+6y^3+8y+4y^2+y^3\\=8+(12y+8y)+(6y^2+4y^2)+(6y^3+y^3)\\=8+20y+10y^2+7y^3$

a submarine travels at an elevation of -75 3/4 ft relative to sea level then its elevation changes by - 16 3/8 what is the new e

slamgirl [31]

Answer:

$New = -92\frac{1}{8}$

Step-by-step explanation:

Given:

$x = -75\frac{3}{4}$ --- Position

$\triangle x = -16\frac{3}{8}$ --- Change

Required

Find the new position

The new position is calculated as:

$New = x + \triangle x$

$New = -75\frac{3}{4} - 16\frac{3}{8}$

$New = -75.75 - 16.375$

$New = -92.125$

$New = -92\frac{125}{1000}$

$New = -92\frac{1}{8}$
