Answer:
the answer will be 14,3 ok but check it
subtract like terms
5a^3 - 6a^3 = -a^3
7 - 4 = 3
answer is -a^3 + 2a^2 - 4a + 3
Answer:
B and C
Step-by-step explanation:
Vertical angles are formed when you make lines make an x shape (or a turned x shape). The vertical angles are, on a normally positioned x the top and bottom angle, as well as the left and right angle. so every x has 2 vertcial angles unless the x is further split up.
So the part with angles 1. 2. 3 and 4 the top angle is 2, the bottom is 3, the left angle is 1 and the right angle is 4. This means the vertical angle pairs are 1 and 4 as well as 2 and 3.
So in total there are 2 x shapes, so 4 pairs of vertical angles. Here are all the vertical angles.
1 and 4
2 and 3
5 and 8
6 and 7
So from your choices you have 2 and 3 as choice B and 5 and 8 as choice C.
Answer:
20% tip is $3.97, add that to 18.97 and you get $22.76, then add 8.25 and you get $31.01
The given radius is = 60 feet
The volume of the sphere is given by = 
So we will find the volume of the sphere using radius as 60 and pi as 3.14
Volume = 
= 902059.20 cubic feet
As quarter of anything is defined as its one-fourth part, so here the volume of the quarter of sphere can be calculated by finding one fourth of the calculated volume.
So volume of quarter sphere = 
= 225514.80 cubic feet
And rounding this to nearest whole number we get 225515 cubic feet as the answer.
