Answer:
A
Step-by-step explanation:
Use foil to expand it.
y = 4 (x^2 + 7x - 9x - 63) Combine the like terms on the right.
y = 4(x^2 - 2x - 63) Use the distributive property to remove the brackets.
y = 4x^2 - 8x - 4*63 Combine the two multiplied factors on the right.
y = 4x^2 - 8x - 252 4* 63 = 252
The answer is A

Answer:
c.
The difference in length between Cassie’s longest and shortest practice sessions was greater than the difference in length between Jacqueline’s longest and shortest sessions.
Step-by-step explanation:
Jacqueline longest time is 45 and the shortest is 30,
45-30=15
Cassie longest time is 50 and the shortest is 15,
50-15=35
35>15
Answer:
it depends
Step-by-step explanation:
The endpoints of the hypotenuse are insufficient to specify a right triangle. The perimeter can range from twice the distance between these points, about 18.868 units, to 1+√2 times the distance between these points, about 22.776 units.
___
In the attached figure, the colored numbers are the total length of the two legs of that color. The hypotenuse and its length are in black.
_____
The distance between two points is given by the formula ...
d = √((x2-x1)^2 +(y2 -y1)^2)
The perimeter will be the sum of the distances between pairs of points that define the vertices of the triangle. We need to know the third vertex to answer the question precisely.
