Multiply.
-zxy (+3528 y?)
Enter your answer in the box.

-3528 xy²z is the product of the given numbers.

Step-by-step explanation:

-zxy × (3528 y)

Here 3528 y is multiplied with -zxy as,

we have to multiply the given number by -1 then the variables x, y and z.

here 2y is present, so it can be multiplied by adding the powers that y¹⁺¹, we will get y², others x and z remains the same.

So we will get the product of, (3528 y) × (-zxy) as -3528 xy²z.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
