3. Rectangle ABCD is shown on the coordinate grid below.
VMariaS [17]

Answer:

A. 8 units

Step-by-step explanation:

Coordinates of A = (-2, -2)

Coordinates of C = (5, 2)

Use distance formula, d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} to calculate the length of diagonal \overline{AC}.

Let,

A(-2, -2) = (x_1, y_1)

C(5, 2) = (x_2, y_2)

d = \sqrt{(5 -(-2))^2 + (2 -(-2))^2}

d = \sqrt{(7)^2 + (4)^2}

d = \sqrt{49 + 16} = \sqrt{65}

d = 8.1 (nearest tenth)

Therefore, the closest to the length of diagonal \overline{AC} = 8 units

PLEASE What fraction of 9 3/8 is 4 3/8 ? (A) 3/8 (B) 7/15 (C) 5/9 (D) 315/8
sattari [20]

Hello!

To solve this, I would convert to improper fractions. This is done by multiplying the integer with the denominator and adding it to the numerator.

9 3/8: 9*8+3=72+3=75

4 3/8: 4*8+3=32+3=35

So the improper fractions therefore are 75/8 and 35/8.

Now to see what fractions of each other they are, you can just divide the numerators because the denominators cancel each other out.

35/75 = 7/15

So your answer would be 7/15, or B.

Hope this helped!

How do you factor quadratic expressions with coefficient and without c?
Volgvan

Answer:

Completing the square. I mean, you can, for some values of a and b, but it's not going to help much if it is messy. Nope!

Factoring. Yes. It's really easy since there is an obvious common factor.

Square root theorem. No idea what this is. And I don't know how it would help.

Quadratic equation. This works, but is a little long for what you have to do.\
