Answer: -10

Step-by-step explanation: From the start of the equation, we know it must factor to something like (3m + x)(n+y), because the first term must be 3mn. Now, for the next term to be -6n, y must be -2, and for the third term to be 5n, x must be positive 5. So we end up with (3m+5)(n-2). If we factor this out, we get 3mn-6m+5n-10, meaning the final term is -10.

??????????????????????

Answer:

$Area = 58 \ units^2$

Step-by-step explanation:

We can start by finding the third side of the triangle/the side of the square using the Pythagorean Theorem:

$a^2+b^2=c^2$

In this case the side length of the square would be represented by the variable "c" as it is the hypotenuse:

$3^2+7^2=c^2$

$9+49=c^2$

$c^2=58$

$c=\sqrt{58}$

Since the area of a square is the side length square then...

$Area =( \sqrt{58} )^2$

The square root and the squared cancel out giving us...

$Area = 58 \ units^2$

Find the measure of the indicated angle. (image included)

kodGreya [7K]

Answer: 88

The unknown angle in the left triangle is 80 since the sum of the angles in a triangle is 180.(180-60-40=80)

The unknown angle (the one that doesn't have a "?") is 36 since there's a straight angle which equals 180.(180-80-64)

Therefore the angle with the "?" is 88 since the sum of the angles in a triangle are 180(180-36-56)

Hope this helps!

Look at the point P on the number line.Which number lines have a point that is equal to pointP? Check all that apply.р

Viktor [21]

In the given Number line the differece between each interval is 10

and the Point P is at -40

Since,

In the graph

A)

the first is -60, then it will be -50 So,

The point P is at -50

Thus the the number line have the same point

B) In the given number line the first point is -60

then -50, -40 and then -30

So, the point is at -30

This number line is not equal to the given number line

C) In the given number line the first point is at -60

and there are three interval so, the the three interval have the values 20

So, the second point will be -40

and the third will be -20

So, the point is at -40

The number line is equal to given number line

D) In the given number line, the interval are divided by 4 parts so

the each interval of the 15 units

the first is at -60

second is at -45

and the point is at -45

So, The number line is not equal to the given number line
