Answer:
-3x^4 - 14x^3 + 3x^2 - 10
Step-by-step explanation:
Answer: -6/4 or 3.66666666666667
1,250 because there’s 25 boxes and each have 50 so you multiple 50x25 to find out how much cards are in each box
Answer: x=15
Step-by-step explanation:
Since these are supplementary angles, we know that if we add them together we would get 180 deg. so....
(7x-10)+ (6x-5)=180
Kay so now we can combine like terms.
13x-15=180
Now we can add 15 to both sides.
13x=195
Finally Divide 13 on both sides.
X would then now equal 15.
Answer: The angle is 105 degrees. This angle along with the 75 degree angle make a straight line , 180-75 = 105 degrees
