Which gives the first two steps to evaluate 3+(2-1)^2×4

According to the order of operations, PEMDAS, 2-1 would be first because it is in parentheses. Next, would be (1)^2 because the second operation is exponents.

First you have to use the method "pemdas".

P=parentheses.

3+(1)^2*4

We go to E.

E= Exponents!!    2*4= 8

3+1^8

3+1=

So the answer would be 4.

AND THE FIRST 2 STEPS TO EVALUATE IS STATED ABOVE.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
