Step-by-step explanation:
10 centimeters to quarters = 0.44 qtr
Answer:
-2 or -5
Step-by-step explanation:
(2x − 8) / (x² + 7x + 10) is an invalid expression when the denominator is 0.
x² + 7x + 10 = 0
(x + 2) (x + 5) = 0
x = -2 or -5
I’m pretty sure that the figure is a rectangle and the two longer sides are 9 centimeters and the shorter ones are 6 centimeters. Rectangles have 4 right angles and all of the side lengths added together equals 30 centimeters
Answer:
-1
Step-by-step explanation:
When the line is slanting down it means its negative.
If it's a quadratic we know that it must look like
for some numbers a,b and c. To find these numbers we use the coordinates.
(0,-2) lies on the curve so when x=0, y=-2

(so that solves one of them)
Next (1,0) lies on the curve so when x=1, y=0

Finally (3,10) lies on the curve so when x=3, y=10

So then we have to solve the simultaneous equations to get a and b

These equations have solutions a=1 and b=1 and so we have a=1, b=1, c=-2.
Therefore the equation of the quadratic is
