Hi there! :)
Answer:
<u><em>*THE ANSWER MUST HAVE A NEGATIVE SIGN!*</em></u>
Step-by-step explanation:
First, you subtract by 8 from both sides of an equation.
5x+8-8=9x+12-8
Subtract.
12-8=4
5x=9x+4
Then, you subtract by 9x from both sides of an equation.
5x-9x=9x+4-9x
Simplify by equation.
-4x=-4
Divide by -4 from both sides of an equation.
-4x/-4=-4/-4
Divide by the numbers from left/right.
-4/-4=-1
, <em>is the FINAL/CORRECT ANSWER! :)</em>

Answer:
29 m
Step-by-step explanation:
The dashes mean that the lines are equal in length, so from this we can determine that the area marked 441 m² is a square.
Area of a square = x², where x is the length of 1 side.
Therefore, x = √441 = 21 m
Now we have a right-angled triangle with two legs of 20 m and 21 m. We need to find the hypotenuse (labelled ?). To do this, use Pythagoras' Theorem a² + b² = c², where a and b are the legs and c is the hypotenuse.
Therefore,
20² + 21² = c²
⇒ 400 + 441 = c²
⇒ 841 = c²
⇒ c = √841
⇒ c = 29
So the side marked ? on the diagram is 29
Pretty sure you have to use the Pythagorean Theorem.
a^2+b^2=c^2
So you would plug in your numbers that you already have (6 and 10) But notice that 10 is the hypotenuse (longest side) so
6^2+x=10^2
Then you would solve it and you should end up with 11.6619
A=p(1+rt)
A=35,000×(1+0.08×7)+7,500×(1+0.105×7)+7,500×(1+0.14×7)=82,462.5
