10a + 5b
How do you write simplified expressions for the area and the perimeter of a rectangle one side 3a other side 5b?
Area: 15ab Perimeter: 2(3a+5b) or as 6a+10b
Is 2(6-3x) plus x equivalent to 2(3x) plus x?
To determine if (2(6-3x) + x) is equivalent to (2(3x) + x), we can simplify both expressions. Starting with the left side: (2(6-3x) + x = 12 - 6x + x = 12 - 5x). Now for the right side: (2(3x) + x = 6x + x = 7x). Since (12 - 5x) is not equal to (7x), the two expressions are not equivalent.
What is 2x with the exponent 2 plus 3x plus 1. what is 7n with the exponent 2 plus 9n plus 2. what is 3x with the exponent 2 plus 8x plus 5. what is 7y with the exponent 2 plus 19y plus 10?
The first and third are quadratic expressions in x, the second is a quadratic expressions in n, and the fourth is a quadratic expressions in y. None of them are equations so cannot be solved.
Are these expressions equivalent 18x2-9x2?
Yes, the expressions (18x^2 - 9x^2) are equivalent. When you simplify (18x^2 - 9x^2), you combine like terms to get (9x^2). Therefore, the expression simplifies to (9x^2).
What is the simplest form for 5b plus 5-3b-7?
5b plus 5-3b-7 is 2b-2.
Are these expressions 15x-9-4x plus 2 and 11x-7 equivalent?
yes
What are two expressions that are equivalent to 8 plus 2x?
(16 + 4x)/2 2(4 + x)
2(a plus b) plus 3(a plus b) plus 5a?
10a + 5b
How do you write simplified expressions for the area and the perimeter of a rectangle one side 3a other side 5b?
Area: 15ab Perimeter: 2(3a+5b) or as 6a+10b
If 8b plus 11-3b equals 2b plus 2 what is b?
8b + 11 - 3b = 2b + 2 5b + 11 = 2b + 2 5b - 2b = 2 - 11 3b = -9 b = -3
How do you factor 30b2 plus 48b-24?
30b^(2) + 48b - 24 Factor out '6' 6(5b^(2) + 8b - 4) Write down the factors of '5', 5 & 1. and '4' ; 4,1, + 2,2 Select a pair of factors that multiply together and then add to arrive at '8' Hence (5 x 2) - ( 1 x 2) = 10 - 2 = 8 Open brackets 6(5b 2)(b 2) Since the '4' is negative aamd the '8' is positive. Then the larger term is positive. Hence 6(5b - 2)(b + 2)
What is a mathematical sentence that shows how 2 expressions are equivalent?
the answer is a(n) equationequationWhen two expressions are equivalent they can form an equation.
Is 2(6-3x) plus x equivalent to 2(3x) plus x?
To determine if (2(6-3x) + x) is equivalent to (2(3x) + x), we can simplify both expressions. Starting with the left side: (2(6-3x) + x = 12 - 6x + x = 12 - 5x). Now for the right side: (2(3x) + x = 6x + x = 7x). Since (12 - 5x) is not equal to (7x), the two expressions are not equivalent.
Which expressions are equivalent to 4b?
