Answer:

a) 10x² - 3x - 18

b) 14x + 6

Step-by-step explanation:

<u>Given:</u>

length = 5x + 6

width = 2x - 3

Tables usually have rectangular shape.

a) Area of the table

<u>Area of a rectangle</u>

A = length × width

Insert values into formula.

A = length × width

A = (5x + 6) × (2x - 3)

A = 10x² - 15x + 12x - 18

A = 10x² - 3x - 18

b) Perimeter of the table

<u>Perimeter of a rectangle</u>

P = 2 × length + 2 × width

P = 2 × length + 2 × width

P = 2(5x + 6) + 2(2x - 3)

P = 10x + 12 + 4x - 6

P = 14x + 6

OLga [1]

Answer:

\frac{13}{20} of the group's video games is either at Jeromes house or Marios  house.

Step-by-step explanation:

Given the statement: Jerome has 1/4 of the group's video games at his house.

Also,Mario has 2/5 of the group's video games at his house.

⇒ Jerome has group's video games at his house(J) = \frac{1}{4}

and

Mario has group's video games at his house(M) = \frac{2}{5}

To find the fraction of the group's video games is either at Jerome house or Mario house.

Between two they have = J+M = \frac{1}{4} + \frac{2}{5} = \frac{5+8}{20} =\frac{13}{20} of the group's video games.

EFGH is a parallelogram. Find the measure of EG.
gayaneshka [121]

Answer: 64

Step-by-step explanation:

If EFGH is a parallelogram, its diagonals bisect each other meaning EJ and JG are congruent.

EJ = JG

4w + 4 = 2w + 18

Subtract 2w from both sides

2w + 4 = 18

Subtract 4 from both sides

2w = 14

Divide both sides by 2

w = 7

EG = EJ + JG

EG = 4w + 4 + 2w + 18

EG = 6w + 22

Now that we know what 'w' is, we can substitute it for 7

EG = 6 (7) + 22

EG = 42 + 22 = 64

The measure of EG is 64.

Hope that helped!
