No, they are both incorrect by my understanding of your question use the Pythagorean theorem a^2 + b^2 =c^, therefore, 7^2 +x^2 = 13^2 or 49+x=169 then solve normally 169-49=120 √120 =5
The answer is 5
Answer:
Step-by-step explanation:
90 + 122 + 4x + 19 + 9x - 8 + 7x - 3 = 540
220 + 20x = 540
-220 -220
--------------------------
20x = 320
/20 /20
----------------
x = 16
Answer:
There are no real roots for this equation.
Step-by-step explanation:
The only solution is irrational: x-√(4-8x)=0
I have provided a graph to help you with this problem.
Hope this helps! :)
10.79/1200=.009
.009*1200=10.79 this is a double check to make sure our price per square foot is correct.
.009*4000=$36.00
It will cost $36.00 to seed the 4,000 square feet at that price.
