The answer would be:
6x - 7
I hope this helped you,
Have a great day
Set them equal to each other and solve
3x + 39 = 4x +34
-x=-5
X=5
Plug it in
3(5) + 39 = 54
4(5) +34 = 54
For the final angle ,
54 + 54 = 108
180-108 =72
The angle measures are 54,54, and 72
Answer:
Area of parallelogram: 1/2×h×sum of base lengths
Property of parallelogram: 2 parallel sides
Area = 1/2×4×(9+9)
= 36 cm^2
Answer:
X^2-18x+81
OR
(X-9)^2
Step-by-step explanation:
X(x-9)-9(x-9)=
x^2-9x-9x+81
X^2-18x+81
The first two are 6 and 28. The factors of 6 add up to the same thing as 6.
Six
1 * 2 * 3 = 6
1 + 2 + 3 = 6
Twenty eight
1 + 2 + 4 + 7 + 14 = 28 (the multiplication is not the same as for 6).
Four hundred ninety Six
This one is kind of hard to believe
It is 16 * 31
1 + 2 + 4 + 8 + 16 + 248 + 124 + 62 + 31 = 496
