Step-by-step explanation:

The perimeter of a rectangle with a length of 9x - 4 and a width of (5x + 2) will be 18x - 4.

Let W be the rectangle's width and L its length. The perimeter of the rectangle will be defined as the total length of all of its sides. So the rectangle's perimeter will be given as,

Perimeter of the rectangle = 2(L + W) units

The dimension of the rectangle is given as,

L = 9x - 4
W = 5x + 2

Then the perimeter of the rectangle is given as,

P = 2(L + W)

P = 2(9x - 4 + 5x + 2)

P = 2(14x - 2)

P = 18x - 4

The perimeter of a rectangle with a length of 9x - 4 and a width of (5x + 2) will be 18x - 4.

Answer: [tex]15\times\frac{1}{2}[/tex]

Explanation:

Multiplying by 1/2 is the same as dividing by 2.

For example, if you have 10 slices of cake and 2 friends, then each friend gets 10/2 = 5 slices. We could also say [tex]10\times \frac{1}{2} = 5[/tex]

The fraction 1/2 converts to the decimal form 0.5, which means [tex]10 \times \frac{1}{2} = 10*0.5[/tex]

1) Answer:

[tex]h = \frac{3}{2} [/tex]

2) Answer:

[tex]a = \frac{160}{3} [/tex]

3) if you mean,

[tex] \frac{3}{5} x = 12[/tex]

Then the answer is. x = 20.

but, if you mean

[tex] \frac{3}{5x} = 12[/tex]

then the answer would be, x = 1/20.

4) Answer:

[tex]y = \frac{5}{7} [/tex]

5) If you mean,

[tex] \frac{14}{3} = - \frac{7}{9b} [/tex]

then the answer would be, b = -1/6

but if you mean,

[tex] \frac{14}{3} = - \frac{7}{9} b[/tex]

then the answer would be, b = -6

First look at each chunk of the question and split up the question into easily readable sections. Make sure you do not confuse the first decimal place as a ones place.

Answer:

rotations, translations, and reflections will not have an effect on a triangles size or shape. They just move it, rotate it, or mirror it.

Only a dilation will change a triangles size. Dilations scale a triangle up or down which change the triangles segment lengths but does not change it's angle sizes.

Answer:

B) 23

Step-by-step explanation:

23 girls x 4 boxes each = 92 boxes

92 + 11 extra = 103

23 girls x 5 boxes each = 115 boxes

115 - 12 = 103

Mrs. Warren has 103 boxes and 23 girls in her Girl Scout troop.

Mrs. Warren has 103 boxes and 23 girls in her Girl Scout troop. so option B is correct.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given; Mrs. Warren has b boxes of Girl Scout cookies that she wants to distribute to the members of her troop.

If she gives each girl 4 boxes, she will have 11 boxes left over then,

23 girls x 4 boxes each = 92 boxes

92 + 11 extra = 103

If she wanted to give each student 5 boxes, she would need an additional 12 boxes then,

23 girls x 5 boxes each = 115 boxes

115 - 12 = 103

Hence, Mrs. Warren has 103 boxes and 23 girls in her Girl Scout troop. so option B is correct.

Answer:

8.25 feet approx

Step-by-step explanation:

Given data

Diameter= 18inches to feet= 1.5 feet

radius= 1.5/2= 0.75 feet

Height= 3 feet

The expression for the total surface area of the barrel(cylinder) is given as

TSA= 2πrh+2πr^2

substitute

TSA= 2*3.142*0.75+ 2*3.142*(0.75)^2

TSA= 4.713+ 6.284*0.5625

TSA= 4.713+ 3.53475

TSA= 8.25 feet

Hence the TSA is 8.25 feet approx
