Answer:
-17
Step-by-step explanation:

To convert a mixed number into an improper fraction<span>, multiply the whole number by the denominator and add it to the numerator. This becomes the numerator of the </span><span>improper fraction, so 3 x 2 = 6 + 5 = 11 so, your answer should be 11/2</span>
Hello!
You first have to find the area of the square grid
To find this you multiply the sides
14 * 14 = 196
Next you have to find the area of the triangle
To find the area of a triangle you use the equation

h is height
b is base
Put in the values you know

Multiply

The area of the triangle is 49 inches squared
You divide the area of the triangle by the area of the square
196 / 49 = 4
The answer is 4 triangles
Hope this helps!
F(x) = -x^2 + 3x + 8
f'(x) = -2x + 3
when f(x) is increasing f'(x) > 0
-2x + 3 > 0
-2x > -3
x < 3/2 or 1.5
So the required interval is (-infinity,1.5).The first choice.
I might be 1.6 I’m not sure
