2_10 i'm guessing means 2/10, so in percentage, it would be 20%
Answer:138
Step-by-step explanation:
First plug in the c and d values into the expression:
6(5)^2-5(4)+8
Remember PEMDAS, so you do 5^2 first getting you 25.
6(25)-5(4)+8
Continue with PEMDAS and multiply -5 and 4, and that gets you -20.
150-20+8
Now you simplify the expression to get: 138.
Answer:
129 degrees
Step-by-step explanation:
4^2 + 7^2 = c^2
This is because we know that the hypotenuse (c) is always diagonal to the right triangle, so the legs are 4 and 2 (a and b). There is your equation!
Good luck!
6x+42+18x-6=180
24x+36=180
180-36=24x=144
X=6
