"7 = 5 x 2" is a false statement under standard arithmetic rules.
An expression that equals -5 could be represented as ( x - 10 ) when ( x = 5 ). Another simple example is ( -2 + (-3) ), which also equals -5. Additionally, the equation ( 3 - 8 ) yields -5.
The expression 3(5) can be simplified by multiplying the two numbers together. Therefore, 3(5) equals 15. Thus, the expression that has the same value as 3(5) is simply 15.
To evaluate the expression (3xy + 4y^3) when (y = 2) and (x = 5), substitute the values into the expression. This gives: [ 3(5)(2) + 4(2^3) = 30 + 4(8) = 30 + 32 = 62. ] Thus, the value of the expression is 62.
The expression for multiplying the difference of 8 and 2 by 5 is written as ( 5 \times (8 - 2) ). This simplifies to ( 5 \times 6 ), which equals 30.

the expression is: 1^2=1 2^2+(2-1)^2=5 3^2+(3-1)^2+(3-2)^2=14

explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
(3 * 3)(2 * 5) (9)(10) 90
5(5) is 25. 3(-2) is (-6). The expression becomes 25 - (-6). When subtracting a negative number, you actually "add the opposite," so the expression is now 25 + 6 (positive 6 is "the opposite" of -6); the value is 31.
-3
To find the value of the expression 4x - 2y + xy when x = -1 and y = 5, we first substitute the values of x and y into the expression. This gives us 4(-1) - 2(5) + (-1)(5). Simplifying this further, we get -4 - 10 - 5, which equals -19. Therefore, the value of the expression is -19 when x = -1 and y = 5.
(3*5)+(6 to the power of 2)+54-5
3*6*2+5+5+54=100
