Answer:
7x^2+4x-5
Step-by-step explanation:
First you want to find 2√5+3√7, which is ≈12.40938989. Then you would square that number and you would get ≈153.9929574 rounding to the nearest number you would get ≈154.
So the answer is ≈154.
Answer:
12
Step-by-step explanation:
From the question, the values of x, y and z are as follows.
x=15, y=3 and z= -2
Now, we are to find the value of the expression
we substitute the values of x, y and z into the expression and simplify
Therefore, value of
E=number of eagles
c=number of condors
ttoal is 480
c+e=480
5 times as many condors and 9 times as many eagles totals 3260
5c+9e=3260
we have
c+e=480
5c+9e=3260
eliminateion
elmiminate c
times first equation by -5
-5c-5e=-2400
add to other equation
-5c-5e=-2400
<u> 5c+9e=3260 +</u>
0c+4e=860
4e=860
divide both sides by 4
e=215
sub back
c+e=480
c+215=480
minus 215 from both sides
c=265
thiis spring is
265 condors
215 eagles
