The figure is a scalene triangle, and the exact length of side a is √13
<h3>How to determine the exact length of side a?</h3>
To calculate the length of a, we make use of the following law of cosine
a² = b² + c² - 2bc * cos(A)
Using the values in the figure, we have:
a² = 3√2² + 5² - 2 * 3√2 * 5 * cos(45)
Evaluate the expression
a² = 18 + 25 - 30
Evaluate the sum and the difference
a² = 13
Take the square root of both sides
a = √13
Hence, the exact length of side a is √13

Answer:
7(5-2)+6
Step-by-step explanation:
difference - subtraction
putting the 7 next to it means that it will multiply times that first
Answer:
x⁴ +2x³ + x² + 12x
Step-by-step explanation:
(x² + 3x)(x² - x +4)
= x²(x²) - x(x²) + 4(x²) + x²(3x) - x(3x) + 4(3x)
= x^4 - x³ + 4x² + 3x³-3x²+12x
= x⁴ +2x³ + x² + 12x
1 oz is equal to 29mL, and when you multiply 29mL with 12, you get 348mL
<span> So, if n=1 there is one sublevel. if n=3 there are three sublevels</span>
