Answer:
18x^2 + 33x - 9
Step-by-step explanation:
to combine, i like using the foil method
3x x 6x = 18x^2
3x x -9 = 27x
1 x 6x = 6x
1 x -9 = -9
and then just combine those together
18x^2 + 27x + 6x -9
and then add the 2 in the middle
18x^2 + 33x - 9
Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
substitute in the formula above
I saw the diagram.
1) radii: CD, CG, CF, CE, CH
2) diameter: DG, EF
3) radius: 14cm/2 = 7cm
4) diameter: 14cm because DG is the diameter, its measure is the measure of the diameter.
5) Circumference = 2 π r = 2 * 3.14 * 7cm = 43.96cm
6) Area = π r² = 3.14 * (7cm)² = 3.14 * 49cm² = 153.86 cm²
Answer:the total discounted price for two dogs to be groomed is 22.75
Step-by-step explanation:
A dog groomer is offering 20% off a full groom for one dog, and 15% off for each additional dog. Normally, a full groom costs $65 for each dog.
If you decide to take your two furry friends to be groomed,
the discount on the first one would be
20/100 × 65 = 0.2 × 65 = 13
the discount on the second one would be
10/100 × 65 = 0.15 × 65 = 9.75
the total discounted price for two dogs to be groomed would be
13 + 9.75 = 22.75
