Answer:
2
Step-by-step explanation:
2x^2 + 8x + 8
factor the 2 out : 2(x^2 + 4x + 4)
2(x + 2)^2
x = -2
Answer:
I believe the value would be 9.
Multiply the first equation by 4 (so that both equations will have 8x terms) and then subtract:
8x-20y = -24
8x +3y = 68
------------
0 -23y = -92
Now divide both sides by -23:
y = 4
Find x by plugging y=4 into either equation:
8x +3(4) = 68
8x = 68 - 12
8x = 56
x = 7
So the answer is ordered pair is (7,4)
The cost of each vegetable is €1.50 per pound
Edward bought 3.25 pounds of carrot.
So the cost of 3.25 pounds of carrots = 3.25 × 1.50 = €4.875
He also purchased 
pounds of beet.
Quantity of beet purchased = 6/5 = 1.2 pounds
So the cost of beet shall be = 1.50 × 1.2 = €1.80
He purchased 0.95 pounds of Broccoli
So the cost of Broccoli shall be = 0.95 × 1.50 = €1.425
Total amount spent = 4.875 + 1.80 + 1.425 = €8.10
Edward spent €8.10 on vegetables.
Hundred dollar bills is 100 dollars so if you have four of them you get 400
ten dollar bills is 10 dollars so if you have 23 of them you have 230
one dollar bills is 1 dollar so if you have 17 of them you 17 dollars
400+230+17= 647
One dime is equal to 10 cents so if you have 46 of them you have $4.60
One penny equals 1 cent so 19 pennies equal 19 cents
$4.60+.19= $4.79
$647+$4.79= $651.79<---- that's your answer
