Which equation results from taking the square root of both sides of (x + 9)2 = 25?
Alex_Xolod [135]

Answer:

√2.37+ 3 √9 = √5. 3 is the last one

x+9 =+25

Step-by-step explanation:

(x+9)2= 25   This means x= 3.5 and the square root of x = √3.5 = 1.87 square root of 9 x 2 = √18 =4.24

We can also see 18+7 =25

√5.65 √5

this is 25 = 5 so it's the last one.

as 2.37+ 3 √9 = √5. 3

Answer:

5

Step-by-step explanation:

Hello!

We put in 2 for x and 6 for y

\frac{2(6)-2}{2}

Now we can solve this

\frac{12 - 2}{2}

\frac{10}{2} = 5

The answer is 5

Hope this helps!

Answer:

1. x^4 -x^3 -4x^2 -3

a1 = -7.4

an = an-1 -13.8  (choice 1)

Step-by-step explanation:

f(x) = x^4 -x^2 +9

g(x) = x^3 +3x^2 +12

We are subtracting

f(x) -g(x) =x^4 -x^2 +9 - ( x^3 +3x^2 +12)

Distribute the minus sign

x^4 -x^2 +9 -  x^3 -3x^2 -12

I like to line them up vertically

x^4      -x^2 +9

-  x^3 -3x^2 -12

-------------------------

x^4 -x^3 -4x^2 -3


2.  a1 = -7.4

To find the common difference, take term 2 and subtract term 1

-21.2 - (-7.4)

-21.2 + 7.4

-13.8

an = an-1 -13.8
