Step-by-step explanation:
Using FOIL,
(2 + √3)(1 + √3)
= (2)(1) + (2)(√3) + (√3)(1) + (√3)(√3)
= 2 + 2√3 + √3 + 3
= 5 + 3√3.
X = [14 -13]
It wants you to solve x + b = c for the first set (b=8, c=22) then solve it for the second set (b =4, c = -9). Then you put those answers in the same places that those numbers were
Answer:
49
Step-by-step explanation:
Answer:
not a solution
Step-by-step explanation:
Substitute p = - 2 into the left side of the equation and if equal to the right side then it is a solution.
7(- 2) - 5 = - 14 - 5 = - 19 ≠ 20
Then p = - 2 is not a solution of the equation
