Janice makes a box in the shape of the rectangular prism. Show your work and explain how you solved using first, next & last

Rama09 [41]

Answer:

The surface area is $376in^2$

Step-by-step explanation:

The surface area of a rectangular prism is calculated using the formula;

$S.A=2[lw+lh+wh]$

The length of the rectangular prism is $l=10in$

The height is $h=6in$

The width is $w=8in$

The surface area

$S.A=2[10(8)+10(6)+8(6)]$

$S.A=2[80+60+48]$

$S.A=2(188)$

$S.A=376in^2$

A sum of 6(3x+8)+32+12x in different ways

Lemur [1.5K]

First you have multiply 6 by both 3x and 8
6*3x = 18x
6*8= 48
18x + 48 + 32 + 12x
now combine like terms
18x + 12x = 30x
48 + 32 = 80
so 30x + 80 is your answer

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

m - 4m = -6

<u>Step 2: Solve for </u><em><u>m</u></em>

Combine like terms: -3m = -6
Divide -3 on both sides: m = 2

<u>Step 3: Check</u>

<em>Plug in m into the original equation to verify it's a solution.</em>

Substitute in <em>m</em>: 2 - 4(2) = -6
Multiply: 2 - 8 = -6
Subtract: -6 = -6

Here we see that -6 does indeed equal -6.

∴ m = 2 is the solution to the equation.

(1.)Find the slope of the line that passes through the given pair of points. (If an answer is undefined, enter UNDEFINED.) (?a +

jekas [21]

Answer:

1. The slope of the line is $m=\frac{-2b+3}{2a}$ .

2. The value of a is 18.

Step-by-step explanation:

If a line passes through two points, then the slope of the line is

$m=\frac{y_2-y_1}{x_2-x_1}$

(1)

It is given that the line passes through the points (-a + 3, b - 3) and (a + 3, -b). So, the slope of the line is

$m=\frac{-b-(b-3)}{a+3-(-a+3)}$

$m=\frac{-b-b+3}{a+3+a-3)}$

$m=\frac{-2b+3}{2a}$

The slope of the line is $m=\frac{-2b+3}{2a}$ .

(2)

If the line passing through the points (a, 1) and (6, 5), then the slope of the line is

$m_1=\frac{5-1}{6-a}=\frac{4}{6-a}$

If the line passing through the points (2, 7) and (a + 2, 1), then the slope of the line is

$m_2=\frac{1-7}{a+2-2}=\frac{-6}{a}$

The slopes of two parallel lines are same.

$m_1=m_2$

$\frac{4}{6-a}=\frac{-6}{a}$

On cross multiplication we get

$4a=-6(6-a)$

$4a=-36+6a$

$4a-6a=-36$

$-2a=-36$

Divide both sides by -2.

$a=18$

Therefore the value of a is 18.
