Answer:
When you solve using quadratic formula you get,
y= 4,-2
Step-by-step explanation:
We can begin by rearranging this into multiplication:
Now we can factor the numerators and denominators:
The factors
(x+4) and
(x+2) cancel out, leaving us with:
Our answer comes out to be:
or
Based on the numerator of the second fraction (since we used its inverse), the denominators of both, and the factors we canceled out earlier, the restrictions are
x ≠ -4, -3, -2, -1, 4
If you are trying to find the area of a rectangle the formula is length times width. So if 5 is your length and 3 is your width, or vice versa, you just multiply them.
5*3=15
In a circle, the distance from the center of the circle to any point on the circumference is the radius of the circle. The radius of the circle is a constant number and does not change from one point to another.
This means that:
OC = OD = radius of circle
6x + 2 = 10x - 16
2+16 = 10x-6x
18 = 4x
x = 4.5
Therefore radius of circle can be calculated by getting length of either OC or OD as follows:
radius of circle = 6(4.5) + 2 = 28 units
Answer:
total number of students is 25
AIZA AND GLAIZA came 60% of the 25 students that is 15th position
A) therefore students which came below them were= 10
B) Students who has scored greater than them were=> 15-2=13 (as they niether got less than 12 nor more than 12.)
