The answer would be 30 cones. How you do it is just divide 15 by 0.5. Then you’ll get 30.

A triangle has a perimeter of 33cm. If the three sides of the triangle are n, 3n−4, and 3n−5, what is the length of each side?

lara [203]

Just did this one.

The perimeter is the sum of the sides.

n + (3n - 4) + (3n - 5) = 33

7n - 9 = 33

7n = 42

n = 6

3n-4=18-4=14

3n-5=13

Check: 6+14+13=33, good

Answer: 6 cm, 14 cm, 13 cm

36 − 9m^2 factorized

STatiana [176]

Answer:

Step-by-step explanation:

Note that the expression is the difference of squares.

36 - 9m² = 6² - (3m)²

6² - (3m)² = (6 + 3m) (6 - 3m)

Answer:

f(-2) = 0

f(1) = 12

f(2) = 5

Step-by-step explanation:

f(-2) will lie in the function $f(x) =x^2 - 4$

$\therefore f( - 2) = {( - 2)}^{2} - 4 = 4 - 4 = 0$

f(1) will lie in the function $f(x) =2x^2 +10$

$\therefore f(1) = 2 {(1)}^{2} + 10 = 2 + 10 = 12$

f(2) will lie in the function $f(x) =5$

$\therefore f(2) = 5$
