Answer:
a. x² + 6x + 9 = -22 + 9
Step-by-step explanation:
they moved the 22 to the right by subtracting it. this leaves a binomial on the left side, which if what you want to solve it.
then they completed the square by dividing b (6) by 2 = 3. then squaring 3 to get 9.
if you added 9 to the left, then you have to add 9 to the right, therefore resulting in -22 + 9.
Answer:
a. $75.60
b. $1335.60
Step-by-step explanation:
A. First convert the percentage to a decimal.
6% = 0.06
Multiply the cost of the computer by the decimal to find the tax paid.
$1260 × 0.06 = $75.60
B. To find the total cost, add the cost of the computer with the tax.
$1260 + $75.60 = $1335.60
SO Area formula is
AREA = length × width
A = L× W
For length:
1cm\0.5m = 22cm/?m We don`t know about the meter.
if we cross multiply the answer will be 11m.
For width:
1cm\0.5m = 14cm\?m We don`t know about the meter.
if we cross multiply the answer will be 7m.
The square meter should be 77
Because 11 × 7 = 77
Answer:
20 meters below sea level
Step-by-step explanation:
The sea level is Reference point, any point below the sea level will be negative and any point above the sea level will be a positive
She started at 27 meters below sea level on Monday =-27 meters
Tuesday she went up 10 meters from -27=-27+10=-17, 17 meters below sea level. She also descended 3 meters below -17 m=-17-3= -20 meters
Final position on Tuesday= -20 meter or 20 meters below sea level
