Answer:
-1.1, 6.1
Step-by-step explanation:
-2X^2+10X+14=0
(-2X^2+10X+14)/-2=0
X^2-5X-7=0
Then use the quadratic formula because you can't factor
Fill in the equations and solve. One should have the plus and the other should have the minus and that's how you get the 2 different answers.
A=1
B=-5
C=-7
I'm assuming you're looking for the dimensions of the plot. I'm going with that. ;) If the length of the plot is 5 meters longer than the width, then L = w + 5. The area for a rectangle is L*w, and we have an area value of 20,000 so our formula is 20000=(w+5)(w) and
. We will bring the 20,000 over by subtraction and set the polynomial equal to 0 to factor and solve for w.
Solving for w we get values of w=138.9 and -143.9. Of course the 2 things in math that will never EVER be negative are time and distance/length, so -143.9 is out. Our width is 138.9 and the length is 138.9 + 5 so the length is 143.9. And there you go! Hope that's what you needed!
Answer:
3.98
Step-by-step explanation:
First, let us go to the second decimal place. the number here is 7, the number after is 5 which is greater than or equal to 5. Thus we round the 7 up to 8 giving us
3.98
Answer:
yeah sure
Step-by-step explanation:
Answer:
<h2>The slope is undefined</h2>
Step-by-step explanation:
The slope of a line given two points can be found by using the formula
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are (-11, -19) & (-11, -10)
The slope is
Any number divided by zero is undefined so the slope of the line here is undefined.
