Step-by-step explanation:
![= > (2a - 3b) + (5b - a) \\ \\ = > 2a - 3b + 5b - a \\ \\ = > 2a - a + 5b - 3b \\ \\ = > a + 2b](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20%282a%20%20-%203b%29%20%2B%20%285b%20-%20a%29%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%3E%202a%20-%203b%20%2B%205b%20-%20a%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%3E%202a%20-%20a%20%2B%205b%20-%203b%20%5C%5C%20%20%5C%5C%20%20%3D%20%20%3E%20a%20%2B%202b)
I. xy + 2y=3 Not linear equation because is grade 2 equation (xy).
II. x-2y = y Are linear equations in two unknowns (x and y).
III. 3x + 2y = 5 Are linear equations in two unknowns (x and y).
<h2>
Corect ansver: C) II and III only</h2><h2>
</h2>
.
13 percent * 5 years = 65
65% of the cheetah population will be lost in 5 years.
100 percent - 65 percent = 35.
35% of the cheetah population will remain in 5 years.
I do not see how this is a high school question, it's easy.
Answer:
try 137
Step-by-step explanation:
it may be congruent since they're parallel
Answer:
AB = 2.25
Step-by-step explanation:
Perimeter of square = 4L
24 = 4L
L = 24/4
L = 6cm
Hence the side length of square is 6cm
Area of square = L^2
Area of square = 6^2
Area of square = 36 sq. cm
Area of square = 1/2 * Area of the trapezium
36 = 1/2 * (AB+3AB)*8
72 = (AB+3AB)*8
72 = 4AB * 8
72 = 32AB
AB = 72/32
AB = 2.25
