Answer: A or C
Step-by-step explanation:
Using division and the graph, the zeroes of the function are given as follows:
- x = -1 with multiplicity 2.
- x = 2/3 with multiplicity 1.
<h3>How do we find all the zeros of the function?</h3>
The function in this problem is defined as follows:
f(x) = -3x³ -4x² + x + 2.
From the graph, we have that x = -1 is a zero of the function, meaning that it can be written as follows:
-3x³ -4x² + x + 2 = (x + 1)(ax² + bx + c).
The other zeros will be the zeros of ax² + bx + c. To find the coefficients, we use a system of equations, hence:
(x + 1)(ax² + bx + c) = -3x³ -4x² + x + 2
ax³ + (a + b)x² + (c + b)x + c = 2.
Hence the coefficients are given by:
Thus the quadratic equation that we have to solve is:
-3x² - x + 2 = 0
3x² + x - 2 = 0.
Hence:
The zeroes of the function are given as follows:
- x = -1 with multiplicity 2.
- x = 2/3 with multiplicity 1.

Answer:
Step-by-step explanation:
a) Perimeter of triangle = x - 3 + 4x + 3 + 3x - 5
= 8x - 5
Perimeter of rectangle = 2 * (2x + 2) + 2* (4x - 1/2 )
= 4x + 4 + 8x - 1
= 12x + 3
b) 8x - 5 : 12x + 3 = 5 :9
9* ( 8x - 5) = 5 * ( 12x + 3)
72x - 45 = 60x + 15
72x - 60x = 15 + 45
12x = 60
x = 60/12
x = 5
c) 2x + 2 = 2*5 + 2 = 10 +2 =12
4x - 1/2 = 4*5 - 1/2 = 20 - 1/2 = (40- 1)/2 = 39/2
Area of rectangle = length * width = 12 * 39/2 = 6 * 39
= 234 Sq.cm
