Answer:
x = 7√2/3
decimal = 3.299831
Step-by-step explanation:
Subtract 1 from both sides
3√2x+1-1=15-1
Simplify
3√2x=14
Divide both sides by 3√2
3√2x/3√2 = 14/3√2
Simplify
x= 7√2/3
0.95 I think this is the answer. If you get it wrong I’m sorry.
Answer: 11.6 units.
Step-by-step explanation:
1. Plot the points as you can see in the graph attached.
2. As you can see, the lenght <em>TA</em> is 3 units.
3. Apply the formula for calculate the distance between two points, to calculate the length<em> TP</em> and <em>TA.</em> The formula is:

4. Therefore, you have:


5. The perimeter is the sum of the the lenght of each side, therefore:

6. To the nearest tenth unit:

Answer:
26
Step-by-step explanation:
the function is f(x), and we need to find f(-2). the only difference between the two terms i gave is the -2 replacing the x. this means that you must replace every x in the first equation with -2. this makes the new function f(-2)=-9(-2)+8. after multiplying the -9 and -2 and adding that product to 8, you come up with your answer: 26.
