Answer:

angle 3 and angle 4 are equal because the diagonals/2 are equal. Angle 4 equals angle 1 due to opposite interior angles thereom. 90 degrees minus 37=53 degrees which is angle 2. Since angle 2 is equal to the angle GKH, 53+53=106 and 180-106=74 degrees, and due to vertical angles, angle 7 is 74 degrees.

5. CD has an endpoint at (2, -1) and a midpoint at (8,3). Which measure is closest to the length of CD?
Alexus [3.1K]

Answer: C

Step-by-step explanation:

the equation for X is

\frac{2+x}{2} =\frac{8}{1}  use proportion to solve

2 + x = 16

x = 14

(14,y)

The equation for Y is

\frac{-1+y}{2} =\frac{3}{1} use proportion to solve

-1 + y = 6

y = 7

(14,7)

now use the distance formula

(14,7) (2,-1)

which gets you 14.4 or C

Transform x2 + 6x + 8 = 0 into the form (x − p)2 = q?
liraira [26]
So hmmm x²+6x+8=0

alrite.. let's do some grouping now
( x² + 6x + [?]²) + 8 = 0

notice above, we have a missing fellow in order to get a perfect square trinomial... hmm who would that be?

let's take a peek at the middle guy of the trinomial.. 6x.. hmmm let's factor it, 2*3*x, wait a minute!  2 * 3 * x... we already have x² on the left-side, since the middle term is just 2 * the square root of the other two terms, that means that the guy on the right, our missing guy must be "3"

alrite, let's add 3² then, however, bear in mind that, all we're doing is borrowing from our very good friend Mr Zero, 0

so if we add 3², we also have to subtract 3², let's do so

(x² + 6x +3² - 3²) + 8 = 0

(x² + 6x +3²) + 8 - 3² = 0

(x+3)²=3² - 8

(x+3)² = 1

The perimeter of a rectangle is 24 inches. Its length is 8 inches longer than its width. What is the length and width of the rec
myrzilka [38]

Answer:

One length = 10

Two length = 20

One width = 2

Two width = 4

Step-by-step explanation:

The perimeter is 24

A rectangle has 4 sides

2 are length

other 2 is width

First, the length is 8 inches longer

there are 2 length so 8 + 8 = 16

That leave 8 inches left

divide 8 by 4 = 2

Add one length together

8 + 2 = 10

2 is the width

How to check you answer:

10 + 10 + 2 + 2 =24
