The answer is 5, hope this helps
Remember
a/b times c/d=(ac)/(bd)
also remember add exponents with similar bases when mutiplying
x^m times x^n=x^(m+n)
(x^4)/3 times (x^2)/3=(x^4 times x^2)/(3*3)=(x^(4+2))/9=(x^6)/9
answer is (x^6)/9
Multiply the first equation by 7 and the second equation by 2, and then add.
Step-by-step explanation:
2f - 5g=-9
-7f + 3g=4
To eliminate any variable , we need to make the coefficients same with different sign and add it
the coefficient of 'f' in first equation is 2
the coefficient of 'f' in second equation is -7
We already have different sign so we make the coefficients same
To make the coefficient same , we multiply the first equation by 7 and second equation by 2
So equation becomes
14f - 35g = -63
-14f + 6g = 8
Now when we add both equations, 'f' gets cancelled
-29g = -55

Step-by-step explanation:
Answer:
∠CDE = 14°
Step-by-step explanation:
Since CE is extended to point F then ∠FED is an external angle of the triangle
The external angle of a triangle is equal to the sum of the 2 opposite interior angles, that is
∠FED = ∠ECD + ∠CDE ← substitute values
4x + 5 = x + 8 + x + 9, that is
4x + 5 = 2x + 17 ( subtract 2x from both sides )
2x + 5 = 17 ( subtract 5 from both sides )
2x = 12 ( divide both sides by 2 )
x = 6
Hence
∠CDE = x + 8 = 6 + 8 = 14°
