Using the above expression, verify the equivalence of your combined expression (8a) and the given expression (3a + 5a) by evaluating both at the given value of a:
a=2
They are both equal to

70

step-by-step explanation:

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100

step-by-step explanation:

6 equilateral triangles

i think the answer is b x = 1, y = 35/2
