The coefficients in the expression are -1 and 9
<h3>How to determine the coefficients?</h3>
The expression is given as:
-x^2 + 9x
In an expression ax, the coefficient is a.
Using the above as a guide, we have:
-x^2 + 9x
The coefficients in the above expression are -1 and 9

Step-by-step explanation:
Answer:
6c - 7 = 5
Step-by-step explanation:
following the steps in the sentence.
because it is 7 less you have a subtraction problem ( -7)
because it is 6 and a number you have a multiplication problem (6c)
it equals 5 (=5)
Triangle is equilateral with sides of 6.
Therefore all angles = 60°
Ht of 30-60-90 is 3sr3 = 5.196
Area of 30-60-90 = 1/2×b×h = 3×5.196
Area = 15.59
Pie slice from each corner = 60/360×pi×r^2, with r = 3
1/6×pi×9 = 4.71 × 3 pie slices = 14.13
So, shaded inner region = area triangle - 3 pie corners = 15.59-14.13
= 1.46
