Answer:
Step-by-step explanation:
f(x) -h(x) = x³ + 2x² -7x - 8 - [4x² - x - 15 ]
= x³ + 2x² - 7x - 8 - 4x² + x + 15
= x³ + 2x² - 4x² - 7x + x - 8 + 15
= x³ - 2x² - 6x + 7
Answer:
220 candy bars
Step-by-step explanation:
Let the number of candy bars sold=c
Let the number of fruit snacks sold=f
A total of 650 items were sold.
Candy bars are sold for $2.50
Fruit snacks are sold for $1.50
Total Income =$1,195
- Therefore: 2.5c+1.5f=1195
We solve the resulting system of equation for c, the number of candy bars sold.
From the first equation, f=650-c
Substitute f=650-c into 2.5c+1.5f=1195
2.5c+1.5(650-c)=1195
2.5c+975-1.5c=1195
Collect like terms
2.5c-1.5c=1195-975
c=220
Therefore, 220 candy bars were sold.
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
4.05, 1.35, 0.45, 0.15, ...
Since it is a geometric sequence.
So, here, a = 4.05
r = 
So, we know the formula for nth term in geometric sequence.
Hence, First option is correct.

Step-by-step explanation:
area of a rectangle = width x length
Given:
- area = 44 m²
- width = 3 2/3 m
- length = m
Substitute given values:
area of a rectangle = width x length
⇒ 44 = 3 2/3 x
⇒ = 44 ÷ 3 2/3
⇒ = 12
