Answer:
x=
Step-by-step explanation:
2+2-1=3
2+2=4
And 4 minus 1 equals 3
Answer:
3rd option
Step-by-step explanation:
( factorise numerator and denominator )
3x² - 3 ← factor out 3 from each term
= 3(x² - 1²) ← x² - 1 is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
x² - 1
= x² - 1²
= (x - 1)(x + 1) , then
3x² - 3 = 3²(x - 1)(x + 1) ← in factored form
--------------------------------
x² - 5x + 4
consider the factors of the constant term (+ 4) which sum to give the coefficient of the x- term (- 5)
the factors are - 1 and - 4 , since
- 1 × - 4 = + 4 and - 1 - 4 = - 5 , then
x² - 5x + 4 = (x - 1)(x - 4)
then
=
← in factored form
Answer:
104 degrees'
Step-by-step explanation:
Find the diagram attached
According to the theorem;
Angle at the vertex is half the angle at its intercepted arc
Given
Angle at the vertex = 52 degrees
Angle at the intercepted arc = arc QR
Hence;
52 = 1/2 arcQR
Cross multiply
52 * 2 = arcQR
104 = arc QR
Swap
arc QR = 104 degrees'
=2/3 x 4 1/5
Change 4 1/5 to improper fraction
=2/3 x 21/5
Multiply the two numerators together and multiply the two denominators together
= (2*21)/(3*5)
=42/15
Convert back to mixed fraction
= 2 12/15
Simplify by dividing 3 into top & bottom
ANSWER:
= 2 4/5 simplest mixed fraction
Hope this helps! :)
