Answer:
1/6 and 3/6
Step-by-step explanation:
a dice has up to 6 sides making it a 1/6 chance for landing ona four. and then making it a 3/6 chance for landing on a even number
Answer: a = 36 and b = 9
Explanation:
(6x-3)(6x+3)
= 36x² - 18x - 18x - 9
= 36x² - 9
(6x-3)(6x+3) = ax² - b
36x² - 9 = ax² - b
a = 36 and b = 9
Hope it helps!
Answer:
The base is 4cm and the height is 5cm.
Step-by-step explanation:
This is a solve the system question. Call H the height of the triangle and B the base. The question tells us:

and

Sub the first equation into the second (as H is already isolated). You will end up with a quadratic equation - solve that any way you wish (e.g. quadratic formula). I've provided the factored form below which shows you the roots:

In this question, we take B=4. You can't have a negative side length so the other answer is eliminated. Now sub the value for B into either of the original equations. I'll use the first, again because H is already isolated:

Answer:
x^2+3x-5=0
Step-by-step explanation:
Divide the whole equation by 2
Answer:
The answer is D because you should starts at -2 on the y-axis and moves up 3 and right 1.
