Làm tính nhân: a, 3/4y^2.4xy^2
b, 2xy.(-xy)
c, -2/3xy^3.(-3/2y^2)
d, 2x. (x^2– 7x -3)
e, ( -2x^3+ 7xy). 4xy^2

i would say c is the best answer, hope it's right!

good luck! =)

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
