50w2−5w+25

Answers

Answer 1

Answer:

49w2+w+53

49 is a perfect square it'll be 7

Step-by-step explanation:

Answer 2

An expression has a leading coefficient that is a perfect square is 49w²+4+53.

What is a perfect square?

A perfect square is a positive integer that is obtained by multiplying an integer by itself. In simple words, we can say that perfect squares are numbers that are the products of integers by themselves.

The term with the highest degree i.e., the term with the largest power of the variable is the leading term. The leading coefficient is the leading term's coefficient.

In the polynomial 49w²+4+53

The highest degree is with the term 49w² is 2, and its coefficient is 49.

49=7×7=7²

So, 49 is the perfect square.

Therefore, option A is the correct answer.

There are two questions :v

Answers

Answer:

Step-by-step explanation:

One

v^2 - 16

This formation is called the difference of squares. That's because there are 2 squares v^2 and 16. The key to this question is the minus sign.

The square root of v^2 = v

The square root of 16 = 4

You get (v + 4)(v - 4)

Let's see what happens when you expand it.

v*v = v^2v*(-4) = - 4vv*(4) = 4v4*-4 = - 16

Look what happens when you add these 4 terms together.

v^2 - 4v + 4v - 16v^2 - 16

is what is left. The two middle terms cancel out.

Two

This one is a perfect square

w^2 + 16w + 64

(w + 8)(w + 8)

Notice both factors are the same. You might wonder how I new that.

w^2 is a perfect square so take the square root.  ....   v      

64 is a perfect square so take the square root    .....    8

Now you have to work backwards to see if it is right.

w*w = w^2w*8 = 8w8*w = 8w8^2 = 64

Adding you get w^2 + 16w + 64 which is what you started with.

Find the area of the shaded region. Use 3.14 for pi.

Answers

Answer:

326

Step-by-step explanation:

First you find the area of the triangles. Since squares have equal sides we know that the triangle has a side of 20 and 12. We plug this information into the formula A=20x12/2 which equal 120 but since we have 2 triangles we multiply by 2 and get 240. Then we find the area of the square which is 400 when you multiply 20x20. Then you find the area of the circle which is 3.14x10^2 which equals 314. You add 240 and 400 to get 640. You subtract 460 from 314 and get 326.

as likely as not.
EXPLANATION: a coin has 2 sides. (usually heads and tails)
50% chance it is heads
50% chance it is tails
50=50.
So it is just as likely to happen as it is likely to not.

When tossing three coins, what is the probability of tossing exactly two tails?

Answers

Answer:

1/3?

Step-by-step explanation:

Answer:OK SO Since the outcome of a coin toss is equiprobable, the probability of getting exactly two tails out of three is equal to the number of ways to get two tails out of three - aka - divided by the total number of possible coin flip outcomes - aka . Ergo, 3/8 is the probability.
