If the expression is (x - y)2, the solution is (7 - -2)2 = (7+2)2 = 92 = 81.
If the expression is x - y2, the solution is 7 - (-2)2 = 7 - 4 = 3.
c = 4, c squared = 16, 3c squared = 48, 48 + 9 = 57.
The vertex of this parabola is at 5 5 When the x-value is 6 the y-value is -1. The coefficient of the squared expression in the parabola's equation is -6.
A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
That's not an equation, it doesn't ask a question, and there's nothing about it that needs an answer. It's an "expression". Its value depends on the value of 'x', and every different value for 'x' gives the expression a different value. If you want to write an equation ... that asks a question ... it needs an 'equals' sign ( " = " ) in it somewhere.
a=64 b=8 (x+16x+64)=(x+8)^2
c = 4, c squared = 16, 3c squared = 48, 48 + 9 = 57.
2 squared is 4 3 cubed is 27 27 plus 4 is 31
The question is ambiguous. If you meant negative (64 squared), the value is -4096, which is a negative integer. If, instead, you meant (negative 64) squared, the value is +4096, a positive integer.
14.2
4 squared is 4 x 4 which equals 16.
Because the value of C equals 13
No because absolute value of negative 8 equals to positive 8
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.
64
It is an expression whose value will depend on the value of the variable x.
No.
10 squared means 10*10 which equals 100.
