Which numbers are perfect squares? Determine their square roots. 5 20 16 49 100 1000

Please help

Only 16

Step-by-step explanation:

The square roots of 5 & 20 are long decimals.

The square root of 49 is 7 but 7 has a decimal square root.

The square root of 16 is 4, 4 is 2 squared.

So 16 is a perfect square.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
