"7 = 5 x 2" is a false statement under standard arithmetic rules.
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.
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.

12 + 5 equals...
(3*5)+(6 to the power of 2)+54-5
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
12 + 5 equals...
(3*5)+(6 to the power of 2)+54-5
3*6*2+5+5+54=100
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.
you test it by giving the letters a value say if X equals 5 and Y equals 7 then you calculate both expressions with that value. If both answers are the same, then the simplified expression is correct, or an equivalent.
-3 + 5 = 2 This is the same as 5-3 = 2.
