Answer:
C
Step-by-step explanation:
∆=b^2-4a*c=1-4*3*(-10)=121>0 có 2x
x1=-b+sprt∆/2a=1+sprt121/2*3=2
x2=-b-sprt∆/2a=1-sprt121/2*3=-5/3

Answer:
A) Volume of Prism = 48 ft cubed
B) Volume of Pyramid = 16 ft cubed
C) 1/3
This equation is true for all rectangular prisms and rectangular pyramids with the same length, same width, and same height.
Step-by-step explanation:
1) find the volume of the prism
2) volume of a prism = Length x Width x Height
3) 4 x 2 x 6 = 48
4) find the volume of the pyramid
5) volume of a pyramid = Length x Width x Height divided by 3
6) 4 x 2 x 6 = 48 divided by 3 = 16
Hope this helps :)
Answer:
x=20 and y=100
Step-by-step explanation:
Using vertical angles, angle 1 and 3 equal each other. Therefore, x=80/4. Then, by using the sum of angle 1 and 3, 160, and using vertical angles again, we can find angle 2, which is (360-160)/2.
Answer:
there are no real solutions
Step-by-step explanation:
The discriminant is (-10)² - 4*6*50 is below zero, hence there are no solutions.
