Angles are named with 3 letters with the vertex listed in the center to go from angle to arc name take the first and last letter from the angle to name it.

For arc to angle insert the letter of the center in between the listed arc endpoints.

Ex2: Arc DF with center X is angle DXF

the length of a rectangle is 2 times in width if the perimeter of the rectangle is 36 in find its length and width

Basile [38]

Answer:

Length=12 inches Width=6 inches

Step-by-step explanation:

X can stand for the width. 2x can stand for the length since it is twice the width. The perimeter would then equal 6x. 6x is equal to 36. Divide by 6 to isolate x. X equals 6 inches. So twice the width would be 12 inches.

A rectangle has a width, w, equal to 6 less than the length, l. Which expressions represent ways to find the perimeter of the re

Irina-Kira [14]

Answer:

4L-12

Step-by-step explanation:

let's assume the length = L

then the width of the rectangle is L - 6

perimeter = 2× (a+b)

where "a" and "b" are the length and the width of the rectangle.

so perimeter = 2× (L + L - 6)

2 × ( 2L - 6)

4L - 12

Use substitution method & show your work.<br>y = x^2 + 3x - 1<br>4x + 1 = y

irina1246 [14]

4x + 1 = x^2 + 3x - 1
4x = x^2 + 3x - 2
0 = x^2 -x - 2
0 = x^2 -x + 1 - 3
0 = (x - 1)^2 - 3
3 = (x - 1)^2
sqrt 3=(x-1) and (-(x-1))
x = 1+sqrt 3 and 1-sqrt 3
sqrt means square root
