Step-by-step explanation:
7. 180 -92 -67 =21. 180-21 = 159
8.180-144 = 36 + 94 = 130 180-130 = 50
Answer:
2x - 3
Step-by-step explanation:
2x² - 7x + 6 / x - 2
Factorise the numerator(quadratic expression).
2x² -7x + 6
Find the factor of (2×6= 12 ) that add up to give -7 , the coefficient of x.
Factors = -4 and -3
Rewrite the equation
2x² -4x -3x + 6
2x(x - 2) -3(x -2)
( 2x - 3)(x - 2)
Therefore the expression would be
(2x -3)(x-2) / (x-2)
(x-2) divides (x-2) to give
= 2x - 3

Answer:
a) (x +2)(x +3)
b) x = -2 or -3
Step-by-step explanation:
a) The constants in the binomial factors will be divisors of 6 that have a sum of 5. You know that ...
6 = 1×6 = 2×3
The sums of these factor pairs are 7 and 5. You want the pair 2, 3. The factors are ...
x² +5x +6 = (x +2)(x +3)
__
b) The solutions to the equation are the values of x that make the factors zero:
(x +2) = 0 ⇒ x = -2
(x +3) = 0 ⇒ x = -3
Answer:
Number 3
Step-by-step explanation:
It is an acute isosceles because all the angles are acute and two sides are congruent.
