Answer:

-14x^2

Step-by-step explanation:

Area is (7x^2)(-14x)

Area is length times width. Length in this case is 7x. Factoring out 7x gives you -14x^2.

Area = (7x)(x)(-14x)

(x)(-14x)= -14x^2

2/3x + 1/6 = -3/4x + 1
kupik [55]
\frac{2}{3} x +  \frac{1}{6}  =  -\frac{3}{4} x + 1

First, simplify \frac{2}{3} x to \frac{2x}{3} / Your problem should look like: \frac{2x}{3} +  \frac{1}{6} =  -\frac{3}{4} x + 1
Second, simplify \frac{3}{4} x to \frac{3x}{4} / Your problem should look like: \frac{2x}{3} +  \frac{1}{6} =  -\frac{3x}{4} + 1
Third, multiply both sides by 12 (the LCM of 3 and 4) / Your problem should look like: 8x + 2 = -9x + 12
Fourth, subtract 2 from both sides. / Your problem should look like: 8x = -9x + 12 - 2
Fifth, simplify -9x + 12 - 2 to -9x + 10. / Your problem should look like: 8x = -9x + 10
Sixth, add 9x to both sides. / Your problem should look like: 8x + 9x = 10
Seventh, add 8x + 9x to get 17x. / Your problem should look like: 17x = 10
Eighth, divide both sides by 17. / Your problem should look like: x =  \frac{10}{17}

Answer as fraction: x = \frac{10}{17}
Answer as decimal: x = 0.5882

Four teachers bought 10 origami books and 100 packs of oragami paper for their classrooms. They will share the cost of the items
Ksenya-84 [330]
They will take the total price and divide it by four. So x will be the price, so the equation will be x/4=total price per person.
