Finding Initial Value Using a Table
Number of Weeks
Weight
(lb)
The table to the right displays the weight progress of a
puppy at the end of week 4. If the relationship between
time and weight is linear, how much did the puppy
weigh at birth?
O 5.5 pounds
O 6 pounds
O 7.5 pounds
O 16 pounds
18.5
21
23.5

step-by-step explanation:

the true ones are a b and d

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
