Answer:

x=2

Step-by-step explanation:

−3(4−x)+3x=3(10−5x)

(−3)(4)+(−3)(−x)+3x=(3)(10)+(3)(−5x)

−12+3x+3x=30+−15x

(3x+3x)+(−12)=−15x+30

6x+−12=−15x+30

6x−12=−15x+30

6x−12+15x=−15x+30+15x

21x−12=30

Step 3: Add 12 to both sides.

21x−12+12=30+12

21x=42

Charles begins finding the volume of a trapezoidal prism using the formula A = One-half(b1 + b2)h to find the prism's base area.

yKpoI14uk [10]

Answer:

The expression that can be used to represent the volume of the trapezoidal prism is $(2x^3+6x^2)$

Step-by-step explanation:

step 1

Find the area of the trapezoidal base

The area of a trapezoid is given by the formula

$A=\frac{1}{2}(b_1+b_2)h$

we have

$b_1=(x+2)\ units\\b_2=(x+4)\\h=x$

substitute

$A=\frac{1}{2}(x+2+x+4)x$

$A=\frac{1}{2}(2x+6)x$

$A=(x+3)x\\A=(x^2+3x)\ units^2$

step 2

Find the volume of the trapezoidal prism

we know that

The volume of the prim is given by

$V=Bh$

where

B is the area of the base

H is the height of the prism

we have

$B=(x^2+3x)\ units^2$

$H=2x\ units$

substitute

$V=(x^2+3x)2x\\V=(2x^3+6x^2)\ units^3$

therefore

The expression that can be used to represent the volume of the trapezoidal prism is

$(2x^3+6x^2)$

4x - 2y = -8 y = 2x + 4 Need help show work

Kruka [31]

Answer:

4x - 2y = -8--------equation 1

y = 2x + 4

or, -2x+y=4---------equation 2

multiply equation 2 by 2 and solving equation 1and2 we get,

4x - 2y = -8

-4x+2y=8
