Answer:
d) 2x^2 + 2x -59
Step-by-step explanation:
(x-8)(x+4) + (x-3)(x+9) *multiply each term (...)(...)*
x^2 - 4x - 32 + x^2 + 6x -27 *combine like terms*
2x^2 +2x - 59
Answer:
v = 2q
Step-by-step explanation:
If this is all is given in the question, then the answer is an equation. If there are numbers given, then plug the numbers into the equation to solve.
Answer:
Volume of right cylinder= 150.72 cu cm
Volume of cone= 314.159 cu cm
Volume of pyramid with base area 16= 160 cu cm
Volume of pyramid with length 3 =48 cu cm
Step-by-step explanation:
Volume of right cylinder = πr²h= 22/7 (4)²3= 150.72 cu cm
Volume of a cone = 1/3 πr²h= 1/3 (22/7) (5)²(12)= 314.159 cu cm
Volume of a pyramid = 1/3 ah= 1/3(16) (30)= 160 cu cm (where a= area and h= height)
Volume of pyramid= 1/3 (3*3)(16)= 48 cu cm
Answer: DB is 5
Step-by-step explanation:
Alright, lets get started.
Since given that AD is parallel to CB.
And AB is parallel to CD.
And the angle A is given as 90°
It means the given figure is a rectangle.
And the diagonals of the rectangle are equal to each other.
So, 
So, 
Hence the answer is 5 ... Answer
Hope it will help :)
Forget about the negative sign. First you have to find a least common denominator. This would be 63. Since we had to multiply 9 by 7 to get 63 we have to multiply the numerator (4) by 7. This gives us a new fraction of 36/63. Since we ha e to multiply 21 by 3 to get 63 we have to multiply 19 by 3. This gives us 57. So now we have 36/63 and 57/63. Then we add the negative sign back in making 57/63 -57/63. Now we add them together. Because one has a negative sign and one is positive the number has to be closer to zero. So the answer is -21/63.
