2x + x = 54 wher x = number of girls
3x = 54
x = 18
18 girls
Answer:
A factor of f(x) is (x + 1).
Step-by-step explanation:
When we put x+1= 0 then we get the value x= -1
This value is then put into the function to find out whether it is a root or not. For a root to exist it must not have a remainder or the remainder must be zero.
Suppose the function is
F(x)= 2x³ - 42x - 40
f(-1)= 2(-1)³ - 42(-1) - 40
f(-1)= -2 + 42- 40
f(-1)= 0
This gives -1 as the root of the function.
The value of a is 9, the correct option is B.
Given
Hank’s teacher asked him to verify that the product (y−3)(y2+3y+9), is a difference of cubes.
<h3>Quadratic equation;</h3>
The equation which has the highest degree is 2 is called quadratic equation;
Where a, b, and c are the constants.
The given polynomial is;
On multiplying the terms;
On comparing;
Hence, the value of a is 9.

<span>To get the Greates Common Factor (GCF) of 175 and 56 we need to factor each value first and then we choose all the copies of factors and multiply them:
</span>
175: 55756: 222 7GCF: 7
<span>The Greates Common Factor (GCF) is: 7</span>
I think it is C) i am sorry if i am wrong
