Answer:
V = 8 cm³
Step-by-step explanation:
This is basically the formula for volume of pyramid:
Volume of Pyramid = 1/3 × Base Area x Height
OR
Volume of Pyramid = (Base Area x Height)/3
V = Bh/3
Given:
B = 4 cm²
h = 6 cm
V = Bh/3
= (4 x 6) / 3
= 24 / 3
V = 8
Hence
V = 8 cm³
If you want to represent this into inches simply divide 8 with 2.54 as
1 cm = 2.54 inches So,
8 cm / 2.54 cm = 3.15 in
To find the zeros of this equation you need to first set it equal to zero
2x2 + 16x - 9 = 0
But since you can't FOIL this equation you need to move the non-variable number over
2x2 +16x = 9
Now solve for x by pulling an x out of the equation
x(2x + 16) = 9
x = 9
2x +16 = 9
2x = -7
x = -7/2
So your zeros would be at x = 9, and -7/2
Answer:
7x-20=2x-3(3x+2)
We move all terms to the left:
7x-20-(2x-3(3x+2))=0
We calculate terms in parentheses: -(2x-3(3x+2)), so:
2x-3(3x+2)
We multiply parentheses
2x-9x-6
We add all the numbers together, and all the variables
-7x-6
Back to the equation:
-(-7x-6)
We get rid of parentheses
7x+7x+6-20=0
We add all the numbers together, and all the variables
14x-14=0
We move all terms containing x to the left, all other terms to the right
14x=14
x=14/14
x=1
Step-by-step explanation:
The diagnonals of a parallelogram bisect each other ,
so
=》 BD = 3x × 2
=》BD = 6x
and there's given that
=》
=》
=》
=》
so, if x = 4 , then the given quadrilateral is a parallelogram.
