The first number in the ordered pair is how many you go across, second is how many you go up. Then place a dot or, technically speaking, a point.
(2t^2−t−8)(2t^2+2t−1)
= (2t^2+−t+−8)(2t^2+2t+−1)
= (2t^2)(2t^2) + (2t^2)(2t) + (2t^2)(−1) + (−t)(2t^2) + (−t)(2t) + (−t)(−1) + (−8)(2t^2) + (−8)(2t) + (−8)(−1)
=4t^4+4t^3−2t^2−2t^3−2t^2+t−16t^2−16t+8
=4t^4+2t^3−20t^2−15t+8
Sorry if I made it too complicated
B is the answer because none of the others will be right and b is the one you should always do when to solve a rea word problem
16 + 36 = 52
unknown side = square root (52)
unknown side = 7.21
or
unknown side = 2 square root (13)
Answer:
$515.35
Step-by-step explanation:
y-hat = 2.009x - 37.131
y-hat = 2.009(275) - 37.131
y-hat = 552.475 - 37.131
y-hat = 515.344
Therefore, the pizza parlor can expect a profit of $515.35 if it sells 275 pizzas.
