Answer:
(2a-b)(2a+b-1)
Step-by-step explanation:
14.9 is rounded to 15 or if you are going by tens then it is 20
To do this, we plug -1 in as x and -3 in as y. If the two sides are equal, (-1, -3) would satisfy y = x + -2. If they aren't equal, it doesn't satisfy the equation. We get:
-3 ? -1 + (-2);
and so,
-3 does indeed equal -3.
Thus, the point (-1, -3) satisfies the equation y = x + -2
Answer:
16.2 kilograms
Step-by-step explanation:
30 300-gram cans = 9000 grams of soup
18 400-gram cans = 7200 grams of vegetables
9000 + 7200 = 16200 grams
1000 grams = 1 kilogram
16200 / 1000 = 16.2 kilograms
2xy + 5x -12y -30
x(2y + 5) - 6( 2y + 5)
(2y+5) (x-6)
