Answer:
12
Step-by-step explanation:
Because < this means less than. So therefore 5 is less than 12
I'll give you a few hints. Area of a rectangle is length times width. We know that length times width is 135 sq ft, so we can express it as:
<span>L * W = 135 </span>
<span>Now, L is 6 feet longer than width (L = 6 + W). Something tells me this is going to involve a quadratic formula then plugging in values into our original equation. </span>
The correct question is
<span>Jack and Jill are trying to find the slope of a line segment connecting two points, (x1, y1) and (x2, y2). Jack uses the formula m = (y2 - y1)/( x2 - x1) . Jill mistakenly uses a different formula, but still gets the right answer. Which formula COULD she have used? A) (x2 - x1)/( y2 - y1) B) (y1 - y2)/( x1 - x2) C) (x1 - x2)/( y2 - y1) D) (y2 - y1)/( x1 - x2)
we know that
the correct formula to calculate the slope is
m=(y2-y1)/(x2-x1)
then
</span><span>if both numerator and denominator multiply it by -1
</span>
m=-(y2-y1)/-(x2-x1)---------> m=[-y2+y1]/[-x2+x1]
m=[y1-y2]/[x1-x2]
therefore
the answer is the option
B) (y1 - y2)/( x1 - x2)

Answer:
B. x = 4
Step-by-step explanation:
The axis of symmetry is the vertical line through the vertex. This parabola has its vertex at (4, -1), so the axis of symmetry is x = 4.
Answer:
10
Step-by-step explanation:
n + n+1 + n+2 + n+3 = 4n + 6
4n + 6 = 34
4n = 28
n = 7
Eldest: n + 3 = 7 + 3 = 10
