1. What is the length of the missing side? 42 mm
56 mm
C?
What is the length of the hypotenuse?
C=
millimeters

70 mm

Step-by-step explanation:

Use PYTHAGOREAN THEOREM: a^2+b^2=c^2

42^2 + 56^2 = c^2

1764 + 3136 = c^2

4900=c^2

square root of 4900 is 70

so, the final answer is 70 mm

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792

i hope this is what you are looking for : )

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
