9a-5x

step by step explanation:

you can only add and subtract numbers that have the same variables.

12a and 3a are related because there variable is both a.

when u subtract 12a-3a you get the answer of 9a using subtraction.

7x and -2x are the second pair of related terms because they also have the same variable (x)

7x-2x is 5x using subtraction.

put the expression together:

9a-5x

hope this helps!

Find the base of the triangle whose area is 2.4 cm² and who is height is 1.6 cm
Karo-lina-s [1.5K]

Formula of the area of triangle: (BxH)/2

So:

1.6B/2 = 2.4

Multiply both sides by 2:

1.6B = 4.8

Divide both sides by 1.6:

B = 3

Complete the square to write 6x2 + 12x + 9 = 0 in the form of a(x − b)2 = c; where a, b and c are integers.
MrMuchimi

Note that the formula is: ax² + b(x) + c =0

You are trying to write it in the form: a(x - b)² = c


Note that:

a = 6

b = 12

c = 9


Plug into corresponding places: 6(x - 12)² = 9


Because you are just telling us to write it in the form a(x − b)² = c, 6(x - 12)² = 9

is your answer




hope this helps

8y - 9 - ( 4y - 5) = 12y - ( 4 + 5y)
kicyunya [14]

8y-9-4y+5=12y-4-5y

4y-4= 7y-4

Add 4 to both sides

4y=7y. The only answer is 0

HELPP!!! Need answer as soon as possible.

Answer:

Option C. The open and closed circles are reversed and the graph shifts up.

Step-by-step explanation:

From the graph of the functions (Attached below) you can check that for the interval 0 ≤x<1 the floor function takes the value 0 everywhere, also it has closed brackets at 0 and open brackets at 1.

On the other hand for the interval 0<x≤1 the ceiling function takes the value 1, also it has open brackets at 0 and closed brackets at 1.

For that reason we conclude that the open and closed circles are reversed and the graph shifts up.
