Answer:

Step-by-step explanation:

Add you like terms. 4x plus 4x equals 8x. Then 5 plus 9 equals 14 so then you have 8x= 14 divide by eight on both sides and there you go.

3/5 = 6/10 because 3/5 x 2/2 = 6 / 10

6 > 7 so 6/10 > 7/10

Therefore: 3/5 >7/10

Three vertices of a parallelogram are shown in the figure below.

a_sh-v [17]

Given:

The three vertices of the parallelogram are (-3,9), (0,-3), (6,-6).

To find:

The fourth vertex of the parallelogram.

Solution:

Consider the three vertices of the parallelogram are A(-3,9), B(0,-3), C(6,-6).

Let D(a,b) be the fourth vertex.

Midpoint formula:

$Midpoint=\left(\dfrac{x_1+x_2}{2},\dfrac{y_1+y_2}{2}\right)$

We know that the diagonals of a parallelogram bisect each other. So, the midpoints of both diagonals are same.

Midpoint of AC = Midpoint BD

$\left(\dfrac{-3+6}{2},\dfrac{9+(-6)}{2}\right)=\left(\dfrac{0+a}{2},\dfrac{-3+b}{2}\right)$

$\left(\dfrac{3}{2},\dfrac{3}{2}\right)=\left(\dfrac{a}{2},\dfrac{-3+b}{2}\right)$

On comparing both sides, we get

$\dfrac{3}{2}=\dfrac{a}{2}$

$3=a$

And,

$\dfrac{3}{2}=\dfrac{-3+b}{2}$

$3=-3+b$

$3+3=b$

$6=b$

Therefore, the fourth vertex of the parallelogram is (3,6).

What is the value of the expression 3 squared times the quantity of 2 cubed + 4 all divided by 2 squared?

antoniya [11.8K]

Answer:

Step-by-step explanation:

Put this into numbers:

$\frac{3^2*(2^3+4)}{2^2}$

Use Order of Operations to simplify. First, you would do the stuff in parentheses which is:

$2^3+4$

Inside of those parentheses first simplify the exponents:

$8 + 4$

Now add

$12$

So the new equation is:

$\frac{3^2*12}{2^2}$

The next step is to simplify the exponents

$\frac{9*12}{4}$

Multiply out the top

$\frac{108}{4}$

Divide this

$27$
