Answer:
Step-by-step explanation:
207
2 thousands+ 2 tens = 2070
divide that by 10
2070÷10= 207
Answer:(X+Y)²
X²+Y² would be greater than X²-Y² since addition gives a greater result than subtraction.
X²+Y² would be greater than 2(X+Y); this is because 2(X+Y) = 2X+2Y, which will be less than X²+Y², since X>Y.
(X+Y)² = (X+Y)(X+Y). This can be simplified using the distributive property:
X(X)+X(Y)+Y(X)+Y(Y) = X²+XY+YX+Y² = X²+2XY+Y². This is greater than X²+Y².

<u>Explanation</u></h3>

- Solve the equation for d-term.
Because we cannot subtract or add up constants and variables, we simply move the same variable term to the same side and constant term to the same constant side.

Substitute d = -11 in the equation.

The equation is true for d = -11.
