The answer is a = 3/4 = 0.75
First get rid of the paranthesis,

Then set the denominators equal:

Then remove the denominators and solve:

Eliminate -12a^2 by adding 12a^2 to both sides:

Take the fourth root of them or take the square root twice:
![\sqrt[4]{256 {a}^{4} } = \sqrt[4]{81} \\ 4a = 3](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B256%20%7Ba%7D%5E%7B4%7D%20%7D%20%20%3D%20%20%5Csqrt%5B4%5D%7B81%7D%20%20%20%5C%5C%20%204a%20%3D%203)
Divide both sides by 4:
Answer:
hi
Step-by-step explanation:
Distance Formula D RT
Use the formula r = d/t. Your rate is 24 miles divided by 2 hours, so: r = 24 miles ÷ 2 hours = 12 miles per hour
Answer:
4x=8
Step-by-step explanation:
4x=32
32/4=8
Answer:
1
Step-by-step explanation:
for the equation of finding y is x - 5 = y
2 - 5 = -3
3 - 5 = -2
4 - 5 = -1
5 - 5 = 0
<u><em>6 - 5 = 1, </em></u> therefore, y is 1
Answer:
21 cm
Step-by-step explanation:
Since this is an isosceles triangle, the two sides with a line through them must have the same value of x. Therefore, you can set up the following equation:
2x+11=53
2x=42
x=21 cm
Hope this helps!
