58 points & brainliest i ! estimate the value of √52. explain how you use perfect squares to come up with your answer.

49 < 52 < 64

sqrt (49) < sqrt (52) < sqrt (64)

7 < sqrt ( 52) < 8

the sqrt(52) is close  to 7

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
