Answer:

Step-by-step explanation:

The perimeter means the sum of all sides. A square has four equal sides, and we know each side is "y".

y + y + y + y

Then simplify that expression. Collect like terms, which are numbers with the same variables. All of them are "y", so combine them by adding.

y + y + y + y

4y Simplified expression

Remember an expression means there is no equal sign.

P = 4y is an incorrect answer.

That would be an equation.

Use the image to complete the equation below

Given:

A figure in which a transversal line intersect the two parallel lines.

To find:

The missing value for the equation $m\angle \_+m\angle BPD=180^\circ$

Solution:

In the given figure, the two parallel lines are line ED and line AB, and CD is the transversal line.

Angle BPC and angle BPD lie on a straight line CD. So,

$m\angle BPC+m\angle BPD=180^\circ$ (Supplementary angles)

Angle APD and angle BPD lie on a straight line AB. So,

$m\angle APD+m\angle BPD=180^\circ$ (Supplementary angles)

Therefore, the required complete equations are $m\angle BPC+m\angle BPD=180^\circ$ and $m\angle APD+m\angle BPD=180^\circ$ .

x²+6x+2=0

$x=\frac{-6 \pm \sqrt{36-8} }{2} \\or~x=\frac{-6 \pm2\sqrt{7} }{2} \\or ~x=-3\pm \sqrt{7} \\h(x)=(x-2)(x^2+6x+2)=(x-2)(x-3+\sqrt{7} )(x-3-\sqrt{7})$

Answer:

The answer is 4.

Step-by-step explanation:

I believe that, if I'm correct, 2 students are equal to 1%. 2 x 35 = 70. 2 x 33 = 66. 70 - 66 = 4 more students. I hope this is correct.

How do you know whether a number is a multiple of another number

vovikov84 [41]

You would know when one number is also a multiple when the other number is a factor of it as well. For example when we see a prime number like 2, there are no factors for this number so it is just a multiple of 1 and 2.
However for numbers like 15 and 25.
We would know ( if you have your times tables memorized) that 15 is a multiple of 1,3, and 5 and 15. 25 is a multiple of 1, 5, and 25.
