plz i am giving away 20

1.

what is the value of 14 – a2 given a = –3?
a. 23
b. 11
c. 8
d. 5

2.

which equation represents “fifteen more than r is sixty-one? ”
a. r + 61 = 15
b. r + 15 = 61
c. r – 15 = 61
d. r – 61 = 15

3.

what is the value of 42 – 2(3 • 5 + 1)?
a. 8
b. 1
c. –16
d. –21

Okay, so on number one I have no idea. I keep getting 20 because 14 - (-3)2 = 14- (-6) which is really 14 + 6=20.

Number 2 is r+15=61

Number 3 I didn't get any of those answers because you have to solve what is in the parenthesis first so3*5= 15+1=16 then you multiply that by two giving you 16*2=32 and 42-32=10

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
