A real numbers are numbers that can be found on a number line, they include both rational and irrational numbers.
We can first solve the equation;
x² - 6x + 9 =0, using completing square method;
x²- 6x + (-3)² = -9 + (-3)²
(x-3)² = 0
x = 3
therefore, both values of x are 3, thus the expression has no real number x is negative.
Answer:
35° , 40° , 105°
Step-by-step explanation:
the sum of the 3 angles in the triangle = 180° , then
3x + x + 40 = 180 , that is
4x + 40 = 180 ( subtract 40 from both sides )
4x = 140 ( divide both sides by 4 )
x = 35
3x = 3 × 35 = 105
the 3 angle measures are 35° , 40° , 105°
Answer:
A
Step-by-step explanation:
X=4
explanation:
-reduce the fraction
-make the numerators equal
-divide both sides by 5
