Answer:

350.82

Step-by-step explanation:

To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.

The rectangle's area (lw):

7.21*14=100.94

The triangle's area (\frac{1}{2}bh):

\frac{1}{2} (6)(8)

\frac{1}{2} (48)=24

Now add up all the sides. (3 Rectangles, 2 Triangles.)

100.94 + 100.94 + 100.94 + 24 + 24

=350.82

The total surface area is 350.82 cm squared.

Rahul solved the equation 2(x – ) – 2 left-parenthesis x minus StartFraction 1 Over 8 EndFraction right-parenthesis minus StartF
Ghella [55]

Rahul use addition property of equality in step 2.

Solution:

The image of the question is attached below.

Step 1:

$2 x-\frac{1}{4}-\frac{3}{5} x=\frac{55}{4}

combine like terms together.

$2 x-\frac{3}{5} x-\frac{1}{4}=\frac{55}{4}

To make the denominator same multiply and divide 2x by 5.

$\frac{10}{5} x-\frac{3}{5} x-\frac{1}{4}=\frac{55}{4}  

Step 2:

$\frac{7}{5} x-\frac{1}{4}=\frac{55}{4}

By addition property of equality, add \frac{1}{4} on both side of the equation.

$\frac{7}{5} x-\frac{1}{4}+\frac{1}{4}=\frac{55}{4}+\frac{1}{4}

Step 3:

$ \frac{7}{5} x=\frac{56}{4}

Step 4:

Multiply by \frac{5}{7} on both side of the equation.

x=10

Hence Rahul use addition property of equality in step 2.

A 15-foot log is split into 2 pieces. How long are the pieces if the longest piece is 1.5ft shorter than two of the shorter piec
Allisa [31]

Answer:

8.25 ft & 6.75 ft

Step-by-step explanation:

So we know it's split into two pieces, right? So normally that would be 7.5 ft each. But one is 1.5 ft longer than the other. So as a result, I divided that by 2 to add 0.75 ft to piece one and subtract 0.75 ft from piece two's length. So, the longer piece is 8.25 ft, and the shorter one is 6.75 ft.
