Step-by-step explanation:
2x + 3 y = 6 by 2
4x - 6y = 3
____________
4x+ 6 y = 12
4x - 6 y = 3
_____________
12 y = 9
y= 12/ 9 = 4 / 3
2X+ 3( 4 / 3 ) = 6
X = I
12^-6/12^7
When dividing the only thing you do is subtract the exponents from each other.
-6-7
In this case, you have to subtract a number from a negative. -6-7 would actually be -6+-7.
-6+-7= -13
12^-13 is the final answer
The answer is A
Explanation
Direct variation means [ y = k x ]
Given . . . 20 = k 4
k = 20/4 = <u>5 .</u>
Answer:
B 14 cm
Step-by-step explanation:
First, rectangle equation formula is w x l which means 4 x 2 = 8 then triangle formula is b x h which base is 4 and height is 3 which gets 6. So 8 + 6 = 14.
