Answer: 3. Distributive
Step-by-step explanation:
Distributive property of multiplication over addition is the only property that is require to multiply an expression to the other expression with two or more than two terms.
For example: a (b+c)= a b+ac , where a,b,c can be any expression.
Given expression: -5(x-3) = -5x +15 , which illustrates the distributive property of multiplication over addition.
Hence, the correct option is 3. Distributive.
The rest of properties cannot work for multiplication over addition as they are used for one operation.
Answer: the answer is d
Step-by-step explanation:
The value of x, the length of the diagonal, to the nearest whole number is 5
To get the value of x from the given diagram, we will use the cosine rule as shown:
c² = a² + b² - 2ab cos Ф
From the given diagram;
a = 6
b = 4
Ф = 55 degrees
Substitute into the formula
c² = 6² + 4² - 2(4)(6)cos 55
c² = 36 + 16 - 48cos55
c² = 52 - 27.53
c² = 24.4
c = 4.94
c = 5 (to the nearest while number).
The value of x, the length of the diagonal, to the nearest whole number is 5
