Step-by-step explanation:

360=95+95+15+7x+15+7x

360-95-95-15-15=7x+7x

140=14x

140/14=x

Which statement shows that when two polynomials 5x − 6 and 6x + 2 demonstrates the closure property when multiplied? a. 30x2 − 2

pogonyaev

Answer: a. 30x^2 − 26x − 12

First write the equation in a form to better help visualize.

(5x - 6)(6x + 2)

Then use distributive property on the second binomial from the first binomial. <em>You multiply 5x by 6x and 2, then multiply -6 by 6x and 2.</em>

5x * 6x = 30x^2 (The answer is raised to the power of 2 because you're adding the invisible exponents, aka exponents of 1)

Then multiply 5x by 2

5x * 2 = 10x

Then you repeat the process but with -6 instead of 5x.

-6 * 6x = -36x (It is not raised to a power of 2 because -6 does not have a variable to include the invisible exponent)

-6 * 2 = -12

Now take all of your answers and put them into 1 equation by the order you did them.

30x^2 + 10x - 36x -12

But wait! The answer can still be simplified. All you have to do is combine like terms. <em>However 30x^2 can't be combined with 10x because 10x isn't raised to the second power, terms can only be combined if they have the same variable and exponent.</em>

30x^2 + (10x - 36x) - 12

30x^2 - 26x - 12

-BARSIC- [3]

Answer:

A quadrilateral become square if all the sides joining the co-ordinate of quadrilateral is equal

Step-by-step explanation:

Here the given co-ordinate of quadrilateral are

G (3, -1) O(1, -6)

L(-4, -4) F(-2, 1)

Line GF = $\sqrt{(3+2)^2+(-1-1)^2}$

GF = $\sqrt{29}$

Similarly for line OG, OL, FL

OG = $\sqrt{(1-3)^2 +(-6+1)^2$

OG = $\sqrt{29}$

OL = $\sqrt{(-4-1)^2+(-6+4)^2}$

OL = $\sqrt{29}$

And

FL = $\sqrt{(-4+2)^} +(-4+1)^2$

FL = $\sqrt{29}$

all the sides of quadrilateral GF, OG, OL, FL all equal to $\sqrt{29}$

As all the sides are equal so quadrilateral become square Answer

HELP ME Write and solve a proportion to find y.

Phoenix [80]

Given:

A figure of dilation and the center of dilation is O.

To find:

The value of y.

Solution:

The distance between center and vertex of image (d') is proportional to the distance between center and the corresponding vertex of original figure (d).

$d'\propto d$
