Answer:
to find the value of c, isolate it.
28 + c = 36
c = 36 - 28
c = 8
now, to check:
28 + 8 = 36 ✓

Determine the length of the legs
To do this, we apply Pythagoras theorem.
In this case:
Open Bracket
Collect Like Terms
Solving using quadratic formula:
So:
or
Since, x can't be negative, then:
One of the leg is:
Answer:
299/60
* I know the answer seems weird but that's the answer and you can check it too.
Step-by-step explanation:
7/2 × 4/3 + 7/12 - 1/5 × 4/3
- First multiply,
28/6 + 7/12 - 4/15
- Then add,
21/4 - 4/15
- Finally Subtract,
<u>299/60</u>
* I know the answer seems weird but that's the answer and you can check it too.

Answer:
Alright so on this type of problem you just perform the operation they ask for, which in this case is subtraction.
Your first step will be to set up the problem:
f(x) - g(x)
Next you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8
Hope this helped!
