What type(s) of symmetry does the figure have? (Check all that apply.)
monitta

2 Answers:  A) line symmetry and B) rotational symmetry

=====================================================

Explanation:

We have line symmetry because we can draw a vertical line down the center, and this is a mirror line. One half folds over the vertical line to match up with the other half. There are other lines of symmetry as well.

We also have rotational symmetry because we can rotate the figure some amount of degrees and have it line up with its original image. The before and after will be identical. This applies to any regular polygon.

The ratio of length to width (measured in inches) in a rectangle is 4∶7. find the length of the rectangle if the area is known t
Len [333]
Hey mate
here is your answer

length and width are given in the ratio are ;(4:7)
area of rectangle = (l×b)
therefore,
4x×7x=700
28x^2=700
x^2=700/28
x^2=25
x=5
length =4x=4×5=20, lenght =20 and width =7x so, 7×5=35 width.....

Explain how to find the missing exponent given the base and the value
drek231 [11]

Answer:

To find the value of missing exponent, we have to split the number which is in other side of equal sign (which is not having power) as the multiple of base of the missing exponent.

On both sides, powers have the same base, so their exponents must be equal.

Step-by-step explanation:

<h3>Problem 1:</h3>

Write the missing exponent:

25=5^x

Let x be the missing exponent.

To find the value missing exponent, we have to split the number which is in the left side as the multiple of the base of the missing exponent.

That is,

25=5*5 or 5^2

Now,

5^2=5^x

Powers have the same base so their exponent must be equal.

Hence the missing exponent is 2
