Answer:
3
Step-by-step explanation:
look at the sides
The correct answer is 14/15. To answer this problem, it would help to change the mixed number into an improper fraction.
1 1/3
4/3 Multiply 3 by 1, and then add 1 and put 4 over 3.
4/3 x 7/10 Now, multiply both numbers by each other. Since we're multiplying, we don't need to find a least common denominator.
28/30 4 x 7 = 28; 3 x 10 = 30
14/15 Since 28 and 30 are divisible by 2, we need to simplify the answer.
The correct answer is 14/15.
Hope this helps!
Answer:
x = 14 units
Step-by-step explanation:
- Distance of both the chords from the center of the circle is 9 units.
- -> Both the chords are equal. (Chords equidistant from the center of the circle are equal)
- Perpendicular drawn from the center of the circle bisects the chord.
- -> Measure of one chord = 7 + 7 = 14 unit
- -> Measure of the other chord = 14 units
Answer:
x>-2
Step-by-step explanation:
-8x+32-16<0
-8x<16
divide both sides by -8
x>-2
that's because when you divide by a negative your inequality sign changes
If you mean "factor over the rational numbers", then this cannot be factored.
Here's why:
The given expression is in the form ax^2+bx+c. We have
a = 3
b = 19
c = 15
Computing the discriminant gives us
d = b^2 - 4ac
d = 19^2 - 4*3*15
d = 181
Note how this discriminant d value is not a perfect square
This directly leads to the original expression not factorable
We can say that the quadratic is prime
If you were to use the quadratic formula, then you should find that the equation 3x^2+19x+15 = 0 leads to two different roots such that each root is not a rational number. This is another path to show that the original quadratic cannot be factored over the rational numbers.
