Answer:
length = 25 feet and width = 17 feet
Step-by-step explanation:
area (A ) = length × width, hence
A = (x + 10)(x + 2) ← expand factors
= x² + 12x + 20
given A = 425, then
x² + 12x + 20 = 425 ( subtract 425 from both sides )
x² + 12x - 405 = 0 ← in standard form
(x + 27)(x - 15) = 0 ← in factored form
equate each factor to zero and solve for x
x + 27 = 0 ⇒ x = - 27
x - 15 = 0 ⇒ x = 15
but x > 0 ⇒ x = 15, therefore
length = 15 + 10 = 25 feet and width = 15 + 2 = 17 feet

Answer: There are 15 possible ways to fill in answers .
Step-by-step explanation:
Given : The number of multiple choice questions = 5
The total number of choices for each question {a, b,
and c} = 3
Now by using the fundamental principle of counting , the number of possible ways to fill in answer is given by :-
Therefore, there are 15 possible ways to fill in answers .
Answer:
y = 3x - 100
Step-by-step explanation:
below signifies that the 100 is negative
so we already know that the submarine is starting at -100 meters, which is going to be the y-intercept
ascend means to rise up signifying that the slope is going to be positive and we already know that the submarine is ascending 3 miles per minute
so the equation would look like this:
y = 3x - 100
