To simplify these expressions, we will use the distributive property. The distributive property states that for any numbers a, b, and c:
a(b + c) = ab + ac
Let's apply this property to each expression:
1. (2x)(10x)
To simplify this expression, we will multiply each term inside the parentheses by the term outside the parentheses:
2x * 10x = 20x^2
So the answer is c. 20x^2.
2. -3m(m + 8)
To simplify this expression, we will first distribute -3m to both terms inside the parentheses:
-3m * m = -3m^2
-3m * 8 = -24m
Combining these terms, we get:
-3m^2 - 24m
So the answer is b. -3m^2 - 24m.
3. 4d(2d - 9)
To simplify this expression, we will again distribute 4d to both terms inside the parentheses:
4d * 2d = 8d^2
4d * -9 = -36d
Combining these terms, we get:
8d^2 - 36d
So the answer is a. 8d^2 - 36d.
4. 5b(6b - 10)
To simplify this expression, we will distribute 5b to both terms inside the parentheses:
5b * 6b = 30b^2
5b * -10 = -50b
Combining these terms, we get:
30b^2 - 50b
So the answer is d. 30b^2 - 50b.
Remember, to simplify expressions, use the distributive property to multiply each term inside the parentheses by the term outside the parentheses, and then combine like terms, if any.
Online, “*” is used to indicate multiplication to avoid confusion with “x” as an unknown.
1. What is x*x?
