Answer:

The answer to your question is 28 = 2 $\sqrt{7}$

Step-by-step explanation:

Data

square $\sqrt{28}$

Process

1.- Find the prime factor of 28

28 2

14 2

7 7

28 = 2 x 2 x 7 or 28 = 2² x 7

2.- Write the prime factors inside the square root

$\sqrt{2^{2}7}$

3.- Express the square root as fractional powers

2²/² 7¹/²

4.- Simplify

2 7¹/²

5.- Express 7¹/² as square root

result 2 $\sqrt{7}$

Let a, b, c, and d be real numbers with a, c 6= 0. Prove that the lines y = ax+b and y = cx + d have the same x-intercept if and

Monica [59]

Step-by-step explanation:

We have got the lines :

$y=ax+b\\y=cx+d$

Both lines intercept the x-axis in the point :

$I = (i_{1} ,i_{2})$

In all point from x-axis the y-component is equal to 0.

$I=(i_{1},o)$

We replace the I point in the lines equations:

$0=a(i_{1})+b \\0=c(i_{1})+d$

From the first equation :

$0=a(i_{1})+b \\-b=a(i_{1})\\i_{1}=\frac{-b}{a}$

From the second equation :

$0=c(i_{1})+d\\ -d=c(i_{1})\\i_{1}=\frac{-d}{c}$

Then $i_{1}=i_{1}$

Finally :

$\frac{-b}{a}=\frac{-d}{c} \\\frac{b}{a}=\frac{d}{c} \\ad=bc$

y = ax + b and y = cx + d have the same x-intercept ⇔ad=bc

Drag a reason to each box to complete this proof. If 12=13x+5 , then x = 21.

Ainat [17]

I think the answers are:

Statement Reason
12=13x+5 Given
7=13x Subtraction Property of Equality
21 = x Multiplication Property of Equality
x = 21 Symmetric Property of Equality

By the way, I'm doing the same exam for Geometry as well. There's a lot of proof questions on there which I'm not good at doing for the reasoning part. If you finish the exam before I do, maybe you can message me what the answers are for some of the questions on there so I know if my answers for the questions are incorrect or not.

Besides that, hope the answer above is correct for you.

On the first day of summer a rainstorm brought 2.29 inches of rain to the area. During the rest of the summer there was 3 times

kkurt [141]

To solve this problem, we simply have to multiply the original inches of rain to that of how many times it was for the rest of summer. So in this case, simply multiply 2.29 by 3, that is:

2.29 inches * 3 = 6.87 inches

Answer:

6.87 inches
