The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on.

The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.

The area of the given letters

J = 0.5 × 8 ft × 6 ft = 24 ft²

K = 8ft × 9ft = 72 ft²

L = 6ft × 9ft = 54 ft²

M = 10ft × 9ft = 90ft²

N = 0.5 × 8 ft × 6 ft = 24 ft²

U = 0.5 × 16 yd × 15 yd = 120 yds²

V = 0.5 × 16 yd × 15 yd = 120 yds²

W = 16 yd × 16 yd = 256 yds²

V = 0.5 × 16 yd × 15 yd = 120 yds²

X = 0.5 × 16 yd × 15 yd = 120 yds²

A = 5 in × 10 in = 50 in²

B = 10 in × 12 in = 120 in²

C = 5 in × 12 in = 60 in²

D = 5 in × 10 in = 50 in²

E = 5 in × 12 in = 60 in²

F = 10 in × 12 in = 120 in²

Find the slope of the line that goes through (-1,2) and (-1,9)

Minchanka [31]

Answer :

Answer is slope m= undefined 

Step-by-step explanation:

Given points are (-1,2) and (-1,9)

$we \: know \: that \: \\ slope = \frac{y2 - y1}{x2 - x1} \\ here \: x1 = - 1 \: \: \: x2 = - 1 \\ y1 = 2 \: \: y2 = 9 \\ on \: substituting \: the \: values \: \\ = \frac{9 - 2}{ - 1 - ( - 1)} \\ = \frac{7}{ - 1 + 1} \\ = \frac{7}{0} \\ = \infty \\ hence \: the \: slope \: is \: undefined$

2(3x - 4) + 10 = 5(x + 4) solving equations from book (geometry common core)

Aleks [24]

Answer:

x = 18

Step-by-step explanation:

Given

2(3x - 4) + 10 = 5(x + 4) ← distribute parenthesis on both sides

6x - 8 + 10 = 5x + 20, that is

6x + 2 = 5x + 20 ( subtract 5x from both sides )

x + 2 = 20 ( subtract 2 from both sides )

x = 18
