Finding the zeros is just factoring the equation. It is also where the parabola crosses the x- axis.
First you need to find two numbers that mutliply to give you -21 and add to give you 4 then you put it into this form:
(x +7)(x-3) set each part equal to zero
x+7=0 and x-3=0 you get:
x=-7 and x=3 your zeros
Answer:
Part A: a coefficient is either 20 or 35, both work. A variable is c or w, again either work. The constant is 23.50.
Part B: He will have $503.50
Part C: The coefficient would change, because the amount per car changes, not the amount of cars.
Step-by-step explanation:
A coefficient goes in front of the variable (which is the letter, usually shown as x). The constant is a number with no variable attached.
We replace c with 20, and w with 12, giving us 20(3)+35(12)+23.50 for our equation. After multiplying, we come up with 60+420+23.50, which equals 503.50.
2340 es divisible por estos números. La resonanica wue entran en este número es porque todos son factores de este número.
Answer:
I think it's 98 square metres.
Step-by-step explanation:
perimeter of base x height = 180
180/2 = 90
90 + area of base = 98
The 3rd one because when you find the absolute value of a number, it will always be positive. So the list would be 3.5, 4.2, 9
