√250 = √(25 * 10) = √(5^2 * 10) = √(5^2) * √10
… = 5 √10
=> <em>a</em> = 5
4.
√(-300) = √(-1 * 3 * 100) = √(-1 * 3 * 10^2) = √(-1) * √3 * √(10^2) = <em>i</em> * √3 * 10
… = 10<em>i</em> √3
=> -<em>a</em> = 10 and <em>b</em> = 3 => <em>a</em> = -10 and <em>b</em> = 3
=> <em>a</em> - <em>b</em> = -10 - 3 = -13
Answer:
you can't figure it out without the expression
The possible length of segment AB is 27 < AB < 81
From the question, we have
In triangle ABC
AC = 27
CB = 54
Using Pythagoras theorem,
AC² = AB² + CB²
54² = AB² + 27²
AB = 47
The possible length of segment AB is 27 < AB < 81
Multiplication:
To determine the sum of two or more numbers, mathematicians multiply the numbers. It is a basic mathematical procedure that is widely used in daily life. Multiplication is used when we need to mix groups of like sizes. Multiplication is a representation of the underlying idea of adding the same number repeatedly. The outcome of multiplying two or more numbers is referred to as the product of those numbers, and the factors are the quantities that are multiplied. Multiplying the numbers makes it simpler to add the same number repeatedly.

-3/10 + -17/10 = -20/10 = -2
Hope that helped!
Answer:
D
Step-by-step explanation:
SOH
sinФ = opposite/hypentenous
sin35 = x/20
0.574 = x/20
cross multiply
x = 20(0.574)
x = 11.48
Round to the nearest tenth.
x = 11.5
