Can you help me with this?
(I will give one of you brainliest)

1) and (between 3 and 4)

Explanation: and are the closest WHOLE squares root to ; any other square roots wouldn't give us a whole number, or they're farther away from

2) and (between -(12) and -(13))

3) and (between -(6) and -(7))

see explanation

Step-by-step explanation:

Consider perfect squares on either side of the radicand

(a)

9 < 12 < 16 , then

< < , so

3 < < 4

(b)

- 144 <  - < - 169

- < - < - , s0

- 12 < - < - 13

(c)

- 36 < - < - , so

- 6 < - < - 7

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

16.80 times .20= 3.36
