Answer:

A=Quadratic B=Exponential C=Quadratic D=Quadratic

Step-by-step explanation:

Quadratic equations follow the formula ax^2+b+c and sometimes c or the third digit in the equation may not be there so C=0.

Exponential equations have exponents that are added to another exponent and supported by the base/coefficient.

Linear Equations have a specific formula which is Ax+By=C such a 2x+4y=8 and solve for both x and y.

There were no linear equations because none were solving for x and y, but most were quadratic equations and one exponential equation.

Explanation:
Slope-intercept form is y=mx+b
-2x+4y=8
-8-2x=-4y
Divide by -4
2+1/2x=y

A triangle has side lengths measuring 2x + 2 ft x + 3 ft, and

Marta_Voda [28]

Answer:

$3x+5 < n < x-1$

Step-by-step explanation:

we know that

The <u><em>Triangle Inequality Theorem</em></u> states that the sum of any 2 sides of a triangle must be greater than the measure of the third side

Applying the Triangle Inequality Theorem

1) $(2x+2)+(x+3) > n$

solve for n

$3x+5> n$

Rewrite

$n$

2) $(x+3)+n> 2x+2$

$n> x-1$

therefore

$3x+5 < n < x-1$
