Answer:

20 + 11 + 5

or 36

Step-by-step explanation:

(20+11) +5

When we add or subtract you can just get rid of the parenthesis (Unless the negative is before the parenthesis)

20+11+5

When we add them together we get :

31 + 5 = 36

a triangle has a base of 15 inches and an area of 82.5 square inches. What is the height of the triangle

horrorfan [7]

Area of a triangle = 1/2 x base x height.

Replace are and base to get:

82.5 = 1/2 x 15 x height

Multiply both sides by 2:

165 = 15 x height

Divide both sides by 15:

Height = 165 / 15

Height = 11 inches.

In the diagram below of parallelogram ABCD with diagonals AC and BD, m∠1=45° and m∠DCB=120°.Whatisthemeasureof∠2?

bixtya [17]

Answer:

15degrees

Step-by-step explanation:

From the given diagram

<1+<2 + <DCB = 180

<1+<2+120 = 180

<1+<2 = 180 - 120

<1+<2 = 60

<2 = 60 - <1

<2 = 60 - 45

<2 = 15degrees

Hence the measure <2 is 15degree

Given the slope of y+2=3(x-7) and a point on the line

zaharov [31]

Hi there!

»»————-　★　————-««

I believe your answer is:

m = 3

(7, -2)

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

The equation given is in point-slope form.

⸻⸻⸻⸻

$y - y_1 = m(x-x_1)\\\\m-\text{slope}\\\\(x_1,y_1)-\text{point}$

⸻⸻⸻⸻

The '3' is in the 'm' spot.

The y value is '-2', (y -(-2)) and the 'x' value is 7.

The point of the line is (7, -2) and the slope is 3.

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
