Foil: (x+9)(3x-4)
QveST [7]

QUESTION 1

The given binomial is;

(x+9)(3x-4)

First terms are multiplied: x\times 3x=3x^2

Outside terms are multiplied: x\times -4=-4x

Inside terms are multiplied: 9\times 3x=27x

Last terms are Multiplied: 9\times -4=-36

This gives us;

=3x^2-4x+27x-36

=3x^2+23x-36

QUESTION 2

We want to factor

6r^5s+4r^4s^2-8r^2s

The HCF is 2r^2s

We factor to get;

2r^2s(3r^3+2r^2s-4)

QUESTION 3;

x^2+x-2=0

Split the middle term;

x^2+2x-x-2=0

Factor

x(x+2)-1(x+2)=0

(x+2)(x-1)=0

(x+2)=0,(x-1)=0

x=-2,x=1

The solutions are;

x=-2 and x=1

These are the x-intercepts of the graph of the function

f(x)=x^2+x-2

2. In the diagram below, set I represents rational numbers, set II represents integers, and set III represents whole numbers. Sh
MrRa [10]

The information about the rational numbers and integers shows that the correct option is C.

<h3>How to explain the information?</h3>

It should be noted that rational numbers are numbers where we can write as a fraction of two integers. Any rational number is in the form a/b where a,b are integers and b is nonzero.

Terminating decimals can be written as a rational number. Something like 3.1 is equivalent to 31/10.

Of the four answer choices, only choice C is correct.

Choice A has the value '3' as a rational number, but it doesn't have it in the set of integers as well. So that's why choice A is incorrect.

Choice B has -3.4 in the set of integers, which is not correct. Integers do not have any decimal portion. The same applies to choice D also. We can rule choices B and D out.

Therefore, the correct option is C.

Answer:

Step-by-step explanation:

(a²-2ab+b²)=(a-b)²

a²+2ab+b²=(a+b)²

i solve b and d

(b)

9x²-36x+36=0

(3x)²+2×3x×-6+(-6)²=(3x-6)²

(d)

a²-b²=(a+b)(a-b)

4x²-81=0
