Answer:

A. 18

Step-by-step explanation:

The area of a trapezoid is given by the formula ...

A = 1/2(b1 +b2)h

Here, the parallel bases have lengths 3 and 9. The height is 3, so the area is ...

A = 1/2(3 +9)(3) = 18

The area of the trapezoid is 18 square units.

Amy and Stephanie were playing a number game. Amy picked a number and told Stephanie that if she added 9 to the number and multi

mrs_skeptik [129]

Answer:

A. 2(x + 9) = 8

Step-by-step explanation:

To solve this problem, we proceed as follows:

- We call "x" the number picked up by Amy:

$x$

- Amy then adds 9 to this number, so we get:

$x+9$

- Then, we multiply this sum by 2, so we get:

$2(x+9)$

- Finally, Amy says that this number is equal to 8:

$2(x+9)=8$

So the correct equation is

A. 2(x + 9) = 8

We can even solve it to find the number. We get:

$2(x+9)=8\\2x+2\cdot 9 = 8\\2x+18=8\\2x+18-18=8-18\\2x=-10\\x=\frac{-10}{2}=-5$

What is the absolute value of –18 19 ? Write your answer as a fraction.

fenix001 [56]

Answer:

$\frac{18}{19}$

Step-by-step explanation:

The absolute value of a number is how far away it is from 0 on the number line. Even though $\frac{-18}{19}$ is a negative number, the absolute value wouldn't be $\frac{-18}{19}$ , because distance can't be negative. Hence the absolute value of $\frac{-18}{19}$ is $\frac{18}{19}$ .

Simplify. 1/3(1−1/4)^2 Enter your answer, as a simplified fraction, in the box.

Slav-nsk [51]

Remember that $(\frac{a}{b})^c=\frac{a^c}{b^c}$

simplify inside parentahsees first

1-1/4=3/4

1/3(3/4)^2=
$(\frac{1}{3})(\frac{3}{4})^2=$
$(\frac{1}{3})(\frac{3^2}{4^2})=$
$(\frac{1}{3})(\frac{9}{16})=$
$\frac{9}{48}=$
$\frac{3}{16}=$
