It’s A (-4,4) just plug the number and that your answer
X^2 - 49 = (x + 7)(x - 7) = x^2 - 7x + 7x = 49 = x^2 - 49
Well in area you multiply and perimeter you add, so right now you are multiplying the measures of the triangle, So you can either write out the problem and solve it or use a calculator to get you answer, but I would say to solve it because you never if the calculator could be wrong, so if you wanna write it out then you write 9 then put the 14 under it and put the 5 under 14 but under the 4 of 14, so basically you are just going to multiply 9 by 14 to get 126 then multiply 126 by 5 to get 630, so now 630 is your final answer
Answer: The volume is 33 cubic centimeters.
Step-by-step explanation:
First find the volume of the square pyramid on top of the cube. To find the volume of the square pyramid you use the volume a^2*h/3 a is the side length of the base of the square pyramid and h is the height all divide by 3.
So we can say that the side length of the base of the square pyramid is 3 because it has the same side length base as the cube.
V= 3^2 * 2 /3
V= 9 * 2 /3
V= 18/3
v= 6
So the volume of the square pyramid is 6 so now we need to find the volume of the cube and add them together.
Volume of the a cube uses the formula s^3 where s is the side length.
V= 3^3
v= 3*3*3
v= 27
The volume of the cube is 27.
Add 6 and 27 to find the total volume.
6 +27 = 33
