If f(x) = 2x+1; Prove f(3+1) =f(3)+f(1)
Proof: 2(3+1)+1 = 2(3)+1 + 2(1)
6+2+1 = 6+1+2
9 = 9
<span>Therefore: f(3+1) =f(3)+f(1)

this is NOT the answer just a question i got on my test its a example</span>

Find the area of the following circles. a. A circle with a 8-inch radius b. A circle with a 10-kilometer radius c. A circle with

Thepotemich [5.8K]

Area of a circle is $A= \pi r^2$ . The first one, a, the radius squared is 8*8=64. So $A=64 \pi$ . If you multiply in pi as 3.14, you'll have 200.96 square inches. The second one, b, the radius squared is 10*10=100. So $A=100 \pi$ square kilometers. If you multiply in pi as 3.14 you'll have 314 square kilometers. The third one, c, the radius squared is 14*14=196. So $A=196 \pi yd^2$ . Or you could multiply in pi as 3.14 to get 615.44 yd squared. For the last one, d, the radius squared is 22*22=484 cm. Therefore, $A=484 \pi cm^2$ , or multiply in 3.14 for pi to get 1519.76 cm squared. There you go!

Answer: g = -4 and h =1 or g= -1 and h = -2

Step-by-step explanation:

If two exponents have the same base and are multiplied together, you will keep the base unchange and add the exponents.

So looking at the equation, the base is 2 for both and they are raised to the powers g and h, meaning that if g and h are added together they have to equal -3.

So find two numbers that their sum is -3.

For example, -1 and -2 add up to -3, -4 and 1 add up to -3.

5x-10x+ 2(3y-2)= 10y-5x + 4

Bas_tet [7]

5x-10x+ 2(3y-2)= 10y-5x + 4

Multiply 2 x 3y and by -2

5x-10x+6y-4=10y-5x+4

You get 6y-4

-5x+6y-4=10y-5x+4

Subtract 10x from 5x to get -5x

6y-4=10y+4

Add 5x to the -5x

6y=10y+8

Add 4 to the other side to get 8

-4y=8

Subtract 6y-10y to get -4y

-4y/-4=8/-4

Divide -4y and 8 by -4 to get y by itself and -2

Y=-2

Divide completely for the question below

juin [17]

Answer:

B) 5x^2

Step-by-step explanation:

$\sqrt{\frac{50x^5}{2x} }$

We can divide 50 by 2, we get 25 and we can cancel out x from x^5.

Therefore, we get

$\sqrt{\frac{25x^4}{1} }$

= √25x^4

When we take the square root of 25, we get 5 and √x^4 = x^2.

Taking the square root, we get

= 5x^2

Answer: B) 5x^2

Thank you.
