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:
the amount have in five years is $1,338
Step-by-step explanation:
The computation of the amount have in five years is shown below
As we know that
Future value = Present value × (1 + rate of interest)^number of years
= $1,000 × (1 + 0.06)^5
= $1,000 × 1.06^5
= $1,338
Hence, the amount have in five years is $1,338
We simply applied the above formula so that the correct value could come

Answer:
9x+8 and 3x+5.
Explanation:
Let the first polynomial = 9x + 8
Let the second polynomial be a+b
Similarly:
Thus, the second polynomial = 3x+5
Therefore, the two polynomials whose difference is 6x+3 are 9x+8 and 3x+5.

Using the velocity formula, it is found that the acceleration is of a = 9.8 m/s².
<h3>What is the velocity formula?</h3>
It is given by the initial velocity plus acceleration multiplied by time, that is:
v(t) = v0 + at.
In this problem, we have that v(0) = 0, t = 2, v(2) = 19.6, hence:
v(t) = v0 + at.
19.6 = 0 + 2a.
2a = 19.6.
a = 19.6/2.
a = 9.8 m/s².
The acceleration is of a = 9.8 m/s².
