Choose all of the expressions that are equal to 6 × 45. A.6 × (40 + 5)
B.4 + 2 × 45
C.(6 × 40) + (6 × 5)
D.(6 + 40) × (6 + 5)
E.6 × (20 + 25)

the answers are

option

A

B

E

Step-by-step explanation:

A. as when we do 40+5=45, so 6 x 45

B. as 4+2=6,so 6 x 45

E.as 20+25=45,so 6 x 45

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
