The shape is a square pyramid, meaning it has one square face and four triangle faces of equal area. Add these areas together to get the total surface area.

Area of Square + 4*Area of Triangle = SA

Area of Square:
2^2=4

Area of Triangle:
0.5*2*3=3

SA=4+4*3
SA=16 meters squared

Answer:

B.

Step-by-step explanation:

First, notice that we can cancel out an x in the second term. Thus:

$\frac{3x^2}{x^2+x} =\frac{3x^2}{x(x+1)} =\frac{3x}{x+1}$

As with the last question, change the sign to multiplication and "flip" the second term:

$\frac{2x-1}{x+1}\cdot \frac{x+1}{3x}$

Multiply straight across:

$=\frac{(2x-1)(x+1)}{(x+1)(3x)}$

Cancel the (x+1) term:

$=\frac{2x-1}{3x}$

Cannot be simplified further.

Jamie is buying 5 concert tickets, and he wants his total cost to be no more than $4 Above or below $80. Which inequality models

kumpel [21]

Answer:

Option C $\left|80-5x\right|\le 4$

Step-by-step explanation:

Let

x ----> the cost of the concert ticket

we know that

The total cost to be no more than $4 Above $80

so

$5x\leq 80+4$

Solve for x

$x\leq \$16.80$

The total cost to be no more than $4 below $80

so

$5x\geq 80-4$

Solve for x

$5x\geq 76$

$x\geq \$15.2$

therefore

The inequality that represent this problem is

$\left|5x-80\right|\le 4$

<u><em>Verify</em></u>

<em>First solution (positive case</em>)

$+(5x-80)\le 4$

$5x\le 80+4$

Solve for x

$x\leq \$16.80$ ----> is ok

<em>Second solution (negative case)</em>

$-(5x-80)\le 4$

Multiply by -1 both sides

$(5x-80)\ge -4$

$5x\geq 80-4$

Solve for x

$5x\geq 76$

$x\geq \$15.2$ ---> is ok

Remember that

$\left|5x-80\right|\le 4$ is equivalent to $\left|80-5x\right|\le 4$

Because is a absolute value

Determine the measures of angles C and D.<br>

Morgarella [4.7K]

Answer:

c = 40 and d = 76

Step-by-step explanation:

this is going to take me a long time to explain but here we go

so you need to do 180 - 116 and get 64.

then create a equation that is like this 7y + 6 + 4y + 64 = 180

when you solve it you get y = 10

then plug in 10 in for y in 4y. and you get 40 for c

do the same for d and you will get 76

pls mark me brainleist because i didnt waster your time.
