Answer: EQUAL

Step-by-step explanation:

Just as you can do the same thing to both sides of an equation, you can do the same thing to both sides of a fraction. 15 = 5*3 and 21 = 7*3. Thus, 5/7=15/21

Hope it helps <3 :)

70 × 20%
70 × .20 = .14

What is the length of AB?

Dovator [93]

Answer:

AB = 5

Step-by-step explanation:

The side opposite the 30 degree angle will have the shortest length. The side opposite the 60 degree angle will be √3 times as long, and the side opposite the 90 degree angle will be twice as long.

In this case we just divide 10 by 2

What are the key aspects of the graph of f(x) = x2 – b2, where b is a real number?

netineya [11]

Given equation is $f\left(x\right)=x^2-b^2$ .

Now we need to find about what are the key aspects of the graph of $f\left(x\right)=x^2-b^2$ , where b is a real number.

We know that square of any number is always positive.

then $b^2$ must be a positive number.

So that means for any real number b, as the value of b increases then graph of f(x) shifts downward by $b^2$ units as compared to the graph of parent function $f\left(x\right)=x^2$
