Answer:
See explanation
Step-by-step explanation:
This question requires an attachment. Since there is none, I'll give a general explanation and proceed to answer the question with the attached figure.
To calculate the scale factor.
First, take the measurement of any of the original length. i.e. F, C, D or E
Next, take the measurement of any of the dilated length. i.e. F', C', D' or E'
Then, divide the dilated length by the original length.
i.e.
To further explain; take the attachment as a point of reference.
We have that:
The equation that represents the given problem is (n-30) + n = 210. The correct option is the first option (n-30) + n = 210
<h3>Linear equation</h3>
From the question, we are to write an equation for the given problem
From the given information,
n = Tom's weight in pounds
If Jim weighs 30 pounds less than Tom
Then,
Jim weighs (n - 30)
Thus,
The sum of their weight is
(n-30) + n
∴ (n-30) + n = 210
Hence, the equation that represents the given problem is (n-30) + n = 210. The correct option is the first option (n-30) + n = 210

Answer:
Option 1 is correct.
Step-by-step explanation:
Given the equation 
we have to choose the best statement describes the above equation.
→ (1)
As, the highest degree of its monomials i.e individual terms with non-zero coefficients is 2.
⇒ Degree of above equation is 2.
hence, the given equation is quadratic equation.
The general form of quadratic equation is
In variable u: 
→ (2)
Now, compare equation (1) with (2), we say that
The equation is quadratic in form because it can be rewritten as a quadratic equation with u substitution u = (x + 5).
Option 1 is correct.
