Answer:
g(x) = - x² - x + 12
Step-by-step explanation:
Given
g(x) = (- x - 4)(x - 3)
Each term in the second factor is multiplied by each term in the first factor, that is
- x(x - 3) - 4(x - 3) ← distribute both parenthesis
= - x² + 3x - 4x + 12 ← collect like terms
= - x² - x + 12 ← in standard form
Answer:
100

Answer:
exActual room size: 8 ft 7 in x 5 ft 2 in
Convert to inches, actual room size: 103 in x 62 in
103" x 62"= 6386 inches / 144 (1 sf) = 44.50 sf + waste factor (44.50 x 1.10) = 49 sf
The same method is used when measuring walls. Measure the area to be tiled on each wall. Add them together and figure the square footage. Add your waste factor and this is the amount needed.
Most vertical applications will require trim pieces which have finished edges, this requires a linear measurement. Trim pieces will be used:
1. Where a tiled surface ends on an open wall leaving an exposed tile edge,
2. Where a vertical surface meets a horizontal, like on the edge of a countertop,
3. Where a vertical surface turns a corner, like on the outside corner of a wall.
Trim pieces and decoratives are typically sold by the piece. To figure the quantity you have to establish the length of the trim piece (i.e. 6" bullnose, 8" decorative liner), then the rule is: Linear Inches/Piece Length = Quantity
Amount of sales tax paid on an item that cost $42.00 is $2.94.
Rate of sales tax paid = 2.94÷42 =0.07 = 7%.
Rate of sales tax paid by Mick is 7%. The question is asking is to find the sales tax he will pay on an item that costs $58 before tax.
Sales Tax paid by Mick on an item costing $58.00 is 7% of $58.00 =0.07 of 58=4.06.
Sales tax paid for an item that costs $58.00 before tax is $4.06.
The area covered by the shadow is given by:
A = (512,000,000) * (0.9 / 100)
A = 4,608,000
Then, since the area is a rectangle we have:
A = (w) * (l)
Where,
w: width
l: long
Substituting we have:
4,608,000 = (w) * (14,500)
Clearing w we have:
w = (4,608,000) / (14,500)
w = 317.7931034
Round to the nearest kilometer:
w = 318 Km
Answer:
The width of such a rectangle would be:
A: 318km
