Answer:

X=4, x=-6

Step-by-step explanation:

subtract the 24 over. Then factor, what multiplies to negative 24 and adds to 2, which is -4 and 6. Your factors are (x-4)(x+6). set each of those to zero. x=4 and x=-6

Kamila [148]

She can divide the 8 cups by the 1/3 cups

Step-by-step explanation:

The next step will be to divide 8 cups by 1/3 cups

This will be:

= 8÷1/3

=8*3/1-------------dividing by a fraction is the same as multiplying by its reciprocal

= 24

Solve the following equation for x. Show each step. 5x + 2 = 3x + 4(2x - 1)

Reptile [31]

Answer:

$x=1$

Step-by-step explanation:

Start with:

$5x+2=3x+4(2x-1)$

Distribute the $4$ into $(2x-1)$ :

$5x+2=3x+8x-4$

Combine like terms:

$5x+2=11x-4$

Add $4$ to both sides of the equation:

$5x+6=11x$

Subtract $5x$ from both sides of the equation:

$6=6x$

Divide both sides of the equation by the coefficient of $x$ , which is $6$ :

$1=x$

$x=1$

Answer:

$\$11.13$

Step-by-step explanation:

step 1

Find the surface area of the cylinder

The surface area of the cylinder is equal to

$SA=\pi r^{2} +2\pi rh$

we have

$r=3/2=1.5\ in$ ----> the radius is half the diameter

$h=5\ in$

assume

$\pi =3.14$

substitute

$SA=(3.14)(1.5)^{2} +2(3.14)(1.5)(5)=54.165\ in^{2}$

Find the cost

$54.165*(0.75)=\$40.62$

step 2

Find the surface area of the square prism

The surface area of the prism is equal to

$SA=b^{2} +4bh$

we have

$b=3\ in$

$h=5\ in$

substitute

$SA=(3)^{2} +4(3)(5)=69\ in^{2}$

Find the cost

$69*(0.75)=\$51.75$

step 3

Find the difference of costs

$\$51.75-\$40.62=\$11.13$
