Solve the equation. Select all that apply.x^2= 121
A
x = 11
B. x=21
C. X = 61
D. x=-11
E. X=-21

Answers

Answer:

x = 11, x = -11

Step-by-step explanation:

I know this is kind of late but the two previous answers were wrong.

We have x² = 121. To find x, we need to get rid of the exponent, and to do this, we can take the square root of both sides:

√x² = √121

x = √121

You might think that x = 11 but remember, x can be negative as well because you can square negative numbers. Basically, every real number has two square roots - a positive and a negative one. So, the answer isn't just x = 11, it's also x = -11 because (-11)² = 121 as well.

x=11

Solve the equation 22=2p -2

Answers

Answer:

p = 12

Step-by-step explanation:

add 2 to both sides of the equation

24 = 2p ( divide both sides by 2 )

p = 12


Answer: p=2


Step-by-step explanation:

22=2p-2

You add two to 22 which will give you 24

24=2p

You want to divide the 2 to get the letter by itself

12=2


What is 1/14 x 28 in simplest form

Answers

7 goes into 14 twice.  7 goes into 28 4 times.  So 28/14 = 4(7)/2(7) [the sevens cancel] = 4/2 = 2

14 times 24=336 and that means that 1/14 is14 in whole numbers

provide working for answers/explain your answer briefly

Answers

Answer:

a=3

b=5

c=6

Step-by-step explanation:

Well,~you~see~it's~all~in~the~mental~workings~and~also~if~you~know~your~\nmultiplication~tables!

we~have:

a* b =15~

Now,~where~does~15~fall~in~our~multiplication~table?~5~and~3!~so~that~\nmeans,~a~is~3~and~b~is~5.

Now,~we~have:

b* c=30

We~already~know~what~the~value~of~b~is~so~in~the~5's~table,~what~number~gives~us\n~30?~6!~so,~we~know~that~c~is~6.

We~also~have:

c* a =18

We~already~know~what~c's~value~and~a's~value~is.~c~is~6~and~a~is~3~so~\nif~we~multiply~them~we~get,~18!

Hope~my~answer~helps!~Have~an~amazing~day~ahead!
