Step-by-step explanation:

15) 5    b. color the objects on the chalkboard green

Step-by-step explanation:

15)

This question needs the Pythagorean Theorem, which is a^2 + b^2 = c^2

a is a leg (opposite line to hypotenuse)

b is a leg (base line)

c is the hypotenuse (the diagonal line.)

3^2 + 4^2 = c^2

9 + 16 = c^2

25 = c^2

then you square root the number to the left to find c

square root of 25 is 5, since 5 x 5 is 25.

c

-by-step explanation:

it would be c

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb
