The volume of a rectangular solid is 180 cubic centimeters. The length is 10 centimeters, and the width is 4 centimeters. Using

boyakko [2]

V = 180 cm3
l = 10 cm
w = 4 cm
h = ?

V=lwh, so to get h, divide equation by lw, to get h=V/(lw).

h = 180/(10*4) = 4.5 cm

6-2x=y 14+3x=y plzzz helllllllllllllllp

pashok25 [27]

Answer:

(- $\frac{8}{5}$ , $\frac{46}{5}$ )

Step-by-step explanation:

Given the2 equations

6 - 2x = y → (1)

14 + 3x = y → (2)

Substitute y = 14 + 3x into (1)

6 - 2x = 14 + 3x ( subtract 3x from both sides )

6 - 5x = 14 ( subtract 6 from both sides )

- 5x = 8 ( divide both sides by - 5 )

x = - $\frac{8}{5}$

Substitute x = - $\frac{8}{5}$ into either of the 2 equations for the corresponding value of y

Substituting into (1)

y = 6 - 2(- $\frac{8}{5}$ ) = $\frac{30}{5}$ + $\frac{16}{5}$ = $\frac{46}{5}$

solution is ( - $\frac{8}{5}$ , $\frac{46}{5}$ )

First you need to expand them
(x^2 + 9) + (2x + 6)
then you add them together

x^2 + 2x + 15
now you can factorise it
