The area of the square is 36 because 6×6=36
The area of the triangles is 108 because (1/2)(6)(9)=27 27×4=108 because there are 4 triangles.

108+36=144
The correct answer is 144

Hope this helped :)

What is an equation of the line that passes through the point (3,-1) and is perpendicular to the equation y=-3x+2
Alex17521 [72]
If it is perpendicular then the slope of it will be:

-3 \times x = -1\\\\x = \frac{1}{3}

y = 1/3 x + b

-1 = (1/3)(3) + b

-1 = 1 + b

b = -2

The equation is:

y = \frac{1}{3}x - 2

What is the answer?
Dmitrij [34]

Answer:

read explanation

Step-by-step explanation:

rearrange equations to form y=mx+b

-2x+4=2y

-x+2=y

-y=-2x-5

y=2x+5

use these equations to find slope and y intercepts, and match those with the right graph

slope of first: -1

slope of second: 2

y-int of first: 2

y-int of second:5

Is it possible to build a triangle with inside angles of 90 degrees , 50 degrees, and 60 degrees?
N76 [4]

Answer:

No

Step-by-step explanation:

Given: Angles of a triangle are equal to 90 degrees , 50 degrees, and 60 degrees

To check : if it possible to build a triangle with given angles

Solution:

According to angle sum property of a triangle, sum of angles of a triangle is equal to 180^{\circ}

Here,

sum of given angles = 90^{\circ}+50^{\circ}+60^{\circ}=200^{\circ}\neq 180^{\circ}

Therefore, it is <u>not possible</u> to construct a triangle with given angles.
