Answer:
none, n = 6
Step-by-step explanation:
3n + 4n = 42
7n = 42
n = 6
1.86 is the answer of 7/10 divided by 3/8
Answer:
m∠A = 106°
Step-by-step explanation:
All three sides of the triangle are given in the question.
To find the measure of included angle A between two sides we will apply cosine formula,
BC²= AB² + AC² - 2(AB)(AC)cosA
(13)² = (10)² + (6)² - 2(10)(6)cosA
169 = 100 + 36 - 120cosA
cosA =
cosA = -0.275
A =
A = 105.96°
A ≈ 106°
Therefore, m∠A = 106° will be the answer.
Step-by-step explanation:
from the way you typed this question, I think you mean
x²-2x + 3 multiplied by x+1
so we have
(x²-2x+3) (x+1)
x³+x²-2x²-2x+3x+3
x³-x²+x+3
