Answer:
1,3 minimum
1,6 minimum
3,1 maximum
Step-by-step explanation:
Locate the h as x and the k as y for y-k=a(x-h)^2
<span>To do that, you need to set it all to zero and factor:
x^2+8x+15 = 0
(x+5)(x+3) = 0
then put both those in parentheses chunks in their own equations
x + 5 = 0
x + 3 = 0
and then simplify
x = -5
x = -3
So the two points where the parabola crosses the x-axis are -5 and -3.</span>
Answer:
20 inches x 26 inches
Step-by-step explanation:
set up an equation: (2x)(x+7)=520
now just solve it
2x^2+14x=520
x^2+7x-260 = 0
factor: (x-13)(x+20)
x = 13 and -20
13 is the only one that works because you can't have a negative side length
13+7=20
13*2=26
lmk if you don't understand how to solve that equation
Answer:
the first one but make sure to divide
Step-by-step explanation:
Answer:
Step-by-step explanation:
If the ruler is divided into 2 equal parts, divide 7 inches by 2
7/2 = 3.5 or 3
