Answer:

D. $x^{2} (x-12) -2(x-12)$

Step-by-step explanation:

Determine the groups: $(x^{3}-12x^{2} )$ - $(2x+24)$

Factor out terms: $x^{2} (x-12) -2(x-12)$

The -2 was factored out in the second group to ensure that both groups had

(x-12).

Salsk061 [2.6K]

Answer:

l = 16 feet

Step-by-step explanation:

P = a + b + c + d.

P = 2x + x + 2x + x = 48

6x = 48

x = 48/6

x = 8 feet

Thus, length = 2x = 2(8) = 16 feet

Yao Xin puts \dfrac{3}{10} 10 3 ? start fraction, 3, divided by, 10, end fraction liters of potting soil in each pot for plantin

slega [8]

Answer:

Step-by-step explanation:

Yao Xin puts $\frac{3}{10}$ liters of potting soil in each pot.

Suppose, the number of pots Yao Xin can fill is $x$

So, <u>the total amount of potting soil</u> in $x$ number of pots will be: $\frac{3}{10}x$ liters.

Given that, she has $5\frac{2}{3} or \frac{17}{3}$ liters of potting soil. So, the equation will be........

$\frac{3}{10}x= \frac{17}{3} \\ \\ x=\frac{17}{3}* \frac{10}{3}= \frac{170}{9}=18\frac{8}{9}$

So, she can fill pots.

35a + 25c = 2660
a = 2c

35(2c) + 25c = 2660
70c + 25c = 2660
95c = 2660
c = 2660/95
c = 28 <=== there were 28 children tickets

a = 2c
a = 2(28)
a = 56 <== there were 56 adult tickets

Right trapezoid WXYZ is shown. Right trapezoid W X Y Z is shown. Sides X Y and W Z are parallel. Angle W is 73 degrees and angle

cestrela7 [59]

Answer:

∠WXY = 107°

Step-by-step explanation:

In a trapezoid, adjacent angles are supplementary, meaning they add up to 180°. ∠W and ∠WXY are adjacent, so they are supplementary. 180° - 73° = 107°.

Another way to do this is to know that there are 360° in a trapezoid. This is a right trapezoid, so two of the angles are 90°. One angle is 73°. 90° + 90° + 73° = 253°. 360° - 253° = 107°.

I hope this helps :))
