Answer:
Length of all 3 sides: 7, 7, and 9
Length of the two sides that have the same length: 7
Step-by-step explanation:
Let the two sides with equal lengths have a length of . We can write the third side as .
The perimeter of a polygon is equal to the sum of all its sides. Since the perimeter of the triangle is 23 meters, we have the following equation:
Combine like terms:
Add 5 to both sides:
Divide both sides by 4:
Therefore, the three sides of the triangle are 7, 7, and 9 and the length of the two sides that have the same length is 7.
Answer:
y = 4x² - 44x + 120
Step-by-step explanation:
The formula to solve this will be;
y = c(x - a)(x - b)
Where;
c is the leading coefficient
a and b are the roots
Now, we are given that the roots are 6 and 5, while leading coefficient is 4.
Thus, equation is;
y = 4(x - 5)(x - 6)
Expanding gives;
y = 4(x² - 5x - 6x + 30)
y = 4(x² - 11x + 30)
y = 4x² - 44x + 120
Answer:
2p + 99q
Step-by-step explanation:
To simplify the expression, combine the like terms. Like terms are terms which have the same variable. Assume 00q is 100q.
6p - 3q + z - 3p + 2q - z - p + 100q
6p - 3p - p = 2p
- 3q + 2q + 100q = 99q
z - z = 0
So the expression is 2p + 99q
