The equation shows that the pastries that must be sold at $3.55 each in order to make a profit is 23.
<h3>How to calculate the expression?</h3>
Let the number of units be represented by x.
Based on the information given, the equation will be:
75 + (0.15 × x) = 3.55 × x
75 + 0.15x = 3.55x
3.55x - 0.15x = 75
3.40x = 75
x = 75/3.40
x = 23
Therefore, the number is 23.

Answer: D) (x+1)(x + 2)(x-3)
This is because the roots are x = -1, x = -2 and x = 3
Simply get all the numbers to each side to have 0 on the right side
x = -1 turns into x+1 = 0
x = -2 turns into x+2 = 0
x = 3 turns into x-3 = 0
The three factors are (x+1), (x+2) and (x-3)
Which leads to (x+1)(x+2)(x-3)

Answer:
The measurement of the other parallel side which is the base of the parallelogram is 4.3 m
Step-by-step explanation:
Mathematically, the area of a trapezoid can be calculated using the formula below;
A = 1/2 (a + b) c
where a and b are the parallel sides and c is the height
We have one parallel sides and the height including the value of the area
Let’s say A = 13
a = 2.2m
h = 4.0 m
Plugging these values, we have;
13 = 1/2(a + 2.2) 4
26 = 4(a + 2.2)
26 = 4a + 8.8
26-8.8 = 4a
4a = 17.2
a = 17.2/4
a = 4.3 m
Y/2 minus x or the other way around. hope this helped ♡♡♡
