If we observe the graph it crosses x-axis at the following points:
1) x = - 2
2) x = - 5
This means, x+ 2 and x + 5 are the factors of the polynomial. A polynomial can be expressed as the product of its factors. So we can express the given polynomial as (x + 2)(x + 5)
Thus the answer to above question is option C
Answer:
Step-by-step explanation:
X=5
Area=lenght times widht
area/length=width
(4x²+12x)/(4x)=width
we can factor out the 4x
4x²+12x=4x(x+3)
so the width is x+3
Answer:
Step-by-step explanation:
Multiply both sides by –2 (which flips the sign):
Divide both sides by 3:
Subtract 4 from both sides:
Make 4 an improper fraction with a denominator of 3:
Subtract:
Answer:
3x+36
2x+5
Step-by-step explanation:
The length is (x+12) and the width is 3
A = l*w
A = (x+12)*3
Distribute
3x+36
Bruce earns x dollars
Elliot earns 5 more than 2 times what Bruce earns
E = 5+2x
Rewriting
E = 2x+5
