Answer:
525 ft sq.
Step-by-step explanation:
Variable.
Length = 2w+5
Width = w
2(l+w)=100
2(2w+5+w)=100
2(3w+5)=100
6w+10=100
w=15
l=35
15*35=525
Answer:
Step-by-step explanation:
Mai:
She subtracted 5x instead of distributing. This is incorrect, because since it is in ( ), it has to be multiplied by 3.
Correct: 3(5x + 9) = 15x + 27
12x + 3 = 15x + 27
Noah:
Added 15x instead of subtracting. This is incorrect, because to combine like terms on each side you would add a negative number and subtract a positive number.
Correct: 12x + 3 = 15x + 27
12x - 15x = 27 - 3
-3x = 24
x = 24 / -3
x = -8
The values of x does f(x) = 0 will be -4,0,2.Option A is corect.
<h3>What is a graph?</h3>
A diagram depicting the relationship between two or more variables, each measured along with one of a pair of axes at right angles.
The graph shows the cubic polynomial equation found as;
⇒(x+4)(x)(x-2)
The points f(x) = 0 is;
⇒(x+4)(x)(x-2)
⇒(-4+4)(0)(2-2)
⇒0
The values of x does f(x) = 0 will be -4,0,2.
Hence, option A is corect.
