Answer:
Answer choice three is correct
:) ur welcome!
You need to add all of these values together. This is 2 + 9 + 4 which gives 15
There are 180° in a triangle. Divide this by 15.
180/15 = 12
Then multiply this by the largest in the ratio; which is 9.
This is 12 x 9 which = 108°.
The largest angle is therefore 108°.
For reference, the ratio in degrees would look like this:
24:108:48, which adds up to 180°.
Answer: (7x^2+144)/x^2
Step-by-step explanation:
f(h(x))=
f(12/x)=
(12/x)^2+7=
12^2/x^2 + 7=
144/x^2 +7=
144/x^2 +7*x^2/x^2=
144/x^2+7x^2/x^2=(7x^2+144)/x^2
Answer:
W = 14, L = 18
Step-by-step explanation:
If L = length and W = width, then:
252 = LW
L = W + 4
Substituting:
252 = (W + 4) W
252 = W² + 4W
0 = W² + 4W − 252
0 = (W + 18) (W − 14)
W = -18 or 14
Since W > 0, W = 14. Which means L = 18.
Step 1: Simplify each side, if needed.
Step 2: Use Add./Sub. Properties to move the variable term to one side and all other terms to the other side.
Step 3: Use Mult./Div. ...
Step 4: Check your answer.
