Factor the expression 100w^2x^2-64y^2z^2

1 answer:

6 0

Notice that this is the difference of 2 squares

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

Here we have a^2 = 100w^2x^2 and b^2 = 64y^2z^2

so a = 10wx and b = 8yz and the factors are

(10wx + 8yz)(10wx - 8yz)

I need to know what the answer is we have to combine like terms 10-4+6(4-2)

Paladinen [302]

Answer:

Step-by-step explanation:

Solve the separate part of the equation first

6(4) 6(-2) would equal 24-12

Add it back in to get: 10 - 4 + 24 - 12

-4-12 and 10+24 are the like terms so

10+24 = 34 and -4-12 = -16

Equation in the end: 34-16

Simplify that to: 34-16 = 18

Help urgent In a class of 35 students 15 of them have cats 16 have dogs 3 hangs none how many probability does have both

dalvyx [7]

Answer:

9/25

Step-by-step explanation:

Number of student who has cat , dog = 25 - 3 = 22

Number of students who has cat and dogs = (15 + 16) - 22

= 31 - 22 = 9

Number of students who has only cats = 15 - 9 = 6

Number of students who has only dogs = 16 - 9 = 7

P(Cat & dog) = 9/25
