Can someone answer these for me i don't understand it

1. -25 - 16m

2. 13x + 14

6. -39 - 8h

7. -180c

Step-by-step explanation:

Step-by-step explanation:

1.) 8(-3) + 8(-2m)

= -24 -16m

2.) 10x +14 + 3x

= 13x +14

6.) -7 -8h - 32

= -8h - 39

7.) -36c -45

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,

mrb

add the numbers under frequency to find the total number:

5 + 8 +7 + 4 + 0 +1 = 25

the answer is 25.
