Answer:

147 cm^2

Step-by-step explanation:

To find the surface area, you would have to add up the area of all shapes:

Area of triangle: 1/2 base*height

Area of square: length*width

----------

square = l*w = 7*7 = 49 cm^2

----------

So since there are 4 triangles, you would have to multiply the result by 4.

triangle = 1/2 7*9 = 49/2 = 24.5

4 triangles = area of 1 triangle * 4 = 4(24.5) = 98 cm^2

----------

add them up, and you get 49 + 98 = 147 cm^2

Solve for x: 12 (x – 4)| + 7 = 25.

Rasek [7]

Question:

Solve for x: $12|x-4|+7=25$ . Fill in both values for x below. Write the greater value for x in the first column.

Answer:

$x=5.5$ and $x=2.5$ are the values for x.

Explanation:

The equation is $12|x-4|+7=25$

Subtracting both sides by 7,

$12|x-4|=18$

Dividing both sides by 12,

$|x-4|=1.5$

Now, we shall write the equation by removing modulus by adding plus and minus on the other side of the equation.

$x-4=1.5$ or $x-4=-1.5$

Solving the equation $x-4=1.5$ , we get,

$\begin{aligned} x-4 &=1.5 \\ x &=1.5+4 \\ x &=5.5 \end{aligned}$ or $\begin{aligned} x-4 &=-1.5 \\ x &=-1.5+4 \\ x &=2.5 \end{aligned}$

Thus, the solutions are $x=5.5$ and $x=2.5$
