8/5 ( 2x + 13 ) - 3 = 22

Alona [7]

Answer:

$x = \frac{21}{16}$ = 1 5/16

[/tex] 1 \frac{5}{16}[/tex]

Step-by-step explanation:

$\frac{8}{5} (2x + 13) - 3 = 22$

Expand

$\frac{16}{5} x + \frac{104}{5} - 3 = 22 \\ \frac{16}{5} x + \frac{89}{5} = 2$

Collect like terms and simplify

$\frac{16}{5} x = 22 - \frac{89}{5} \\ \frac{16}{5} x = \frac{21}{5}$

Cross Multiply

$80x = 105$

Divide both sides of the equation by 80

$\frac{80x}{80} = \frac{105}{80} \\ x = \frac{21}{16}$

The surface area of the box will be 112 in²

Explanation

According to the given diagram, the shape of the box is Right Rectangular prism.

The formula for the surface area is :

$A= 2(w*l+h*l+h*w)$ , where $l=$ length, $w=$ width and $h=$ height of the rectangular prism

Given in the diagram that, $l= 8, w=4 , h=2$

So, plugging the values into the formula...

$A= 2(4*8+2*8+2*4)\\ \\ A= 2(32+16+8)\\ \\ A=2(56)\\ \\ A=112$

So, the surface area of the box is 112 in²

Answer:

$m$

$m$

Step-by-step explanation:

we have that

$m$

$m$

$m$ ------> by supplementary angles

Substitute the values and solve for x

$8x-1+9x-6=180\°$

$17x-7=180\°$

$17x=187\°$

$x=11\°$

Find the value of angle R

$m$

Find the value of angle Q
