15/2 r -40, the first answer
Answer:
19 cups of water.
Step-by-step explanation:
1:2 ratio
1=9.5
2=9.5*2= 19
$14.50 because your equation would be 4+1.50(7)=$14.50.
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.
The constant term in the equation is -20 because you will always be subtracting 20 no matter how big x is
