Solve for v 3(2v+5=33 simplify as much as possible
vredina [299]

3(2v+5)=33

Simplify both sides of the equation

3(2v+5)=33

Distribute

(3)(2v)+(3)(5)=33

6v+15=33

Subtract 15 from both sides

6v+15-15=33-15

6v=18

Divide both sides by 6

6v/6=18/6

V= 3


I hope that's help !

In the figure below, the two triangular faces of the prism are fight triangles with sides of length 3, 4, and 5. The other three
olasank [31]
The figure of the prism is attached below.

The total surface area of the prism equals the sum of areas of two triangles and the three rectangles.

Surface Area of Prism = Area of 2 Triangles + Area of 3 Rectangles.

Area of a Triangle = 0.5 x Base x Height
Area of a Triangle = 0.5 x 3 x 4 = 6 square units

There are 3 rectangles. From the figure we can see that the bottom most rectangle has the dimensions 4 by 6. The left most rectangle has the dimensions 3 x 6 and the right most rectangle has the dimensions 5 by 6.

So, the Area of 3 rectangles will be = (4 x 6) + (3 x 6) + (5 x 6) = 72 square units

The Surface Area of the prism will be:

Surface Area = 2 (4) + 72 = 84 square units

Thus the correct answer is option A

How do I solve the problem?
Irina-Kira [14]
Sal: 25 +5x = 240

Divide 5 from both sides so it would be 5+ x=240/5
Subtract 5 from both sides x=48-5
X= 43

Elena: 15 + 5x=300

Divide 5 from both sides so it would be 3 +x=300/5
Subtract 15 from both sides x=60-3
X=57

So Sal jogged for 43 minutes. While Elena jogged for 57 minutes
