Answer:

3x+2

Step-by-step explanation:

9x^2 + 12x +4

This is a perfect square trinomal

(3x)^2 + 12x +2^2 = 3x*2   doubled = 6x*2 = 12x

The middle term is twice the ends

a^2 +2ab+b^2 = (a+b)^2

(3x)^2 + 12x +2^2  = (3x+2) ^2

PROBLEM 2 The height of a golf ball in feet can be determined using the formula h(t) = -16t2 + 100x , where t is the number of s
wolverine [178]

Answer:

<h3>H. 150 ft</h3>

Step-by-step explanation:

Given the height of a golf ball in feet modelled by the formula h(t) = -16t² + 100x where t is in seconds, we are to find the height of the golf after 2.5 seconds. To do that we will simply substitute t = 2.5secs into the formula given;

h(t) = -16t^2 + 100x\\\\h(2.5) = -16(2.5)^2 + 100(2.5)\\\\h(2.5) = -16(6.25) + 250\\\\h(2.5) = -100+250\\\\h(2.5) = 150\\\\

Hence the height of the golf after 2.5 seconds is 150ft.

The equation of line AB is y = 2x + 4. Write an equation of a line parallel to line AB in slope-intercept form that contains poi
bazaltina [42]

Answer:

The equation would be y = 2x - 8

Step-by-step explanation:

The equation of the line would have a slope of 2, since parallel lines have the same slope. We can use that and the point in point-slope form to find the equation.

y - y1 = m(x - x1)

y + 2 = 2(x - 3)

y + 2 = 2x - 6

y = 2x - 8

I don’t understand at all
mariarad [96]
A=1/2ab
Replace the variables with their value
15=1/2(3/2)b
Multiply 1/2 and 3/2
\frac{1}{2}  \times  \frac{3}{2 }  =  \frac{3}{4}
15=3/4b
Divide 3/4 on both sides
15/(3/4) is the same thing as
\frac{15}{1 }  \times  \frac{3}{4}  =  \frac{45}{4}
45/4=b
