The system:
- 12 c + 3 d = 6
- 3 c + 6 d = - 9
----------------------
The 1st equation:
- 12 c = - 3 d + 6 / * ( - 1) ( multiple both sides by -1 )
12 c = 3 d - 6 / : 12 ( divide both sides by 12 )
c = d / 4 - 1/2
Answer:
C ) c = 1/4 d - 1/2
Answer:
-14, -13, -7, 11
Step-by-step explanation:
x + 10 = -4 ----> x = -14
x + 10 = -3 ----> x = -13
x + 10 = 3 ----> x = -7
1 + 10 = x ----> x = 11
Answer:
Surface Area = 2×(3.4×18 + 3.4×30.6 + 18×30.6) = 1432.08 centimeters2
Step-by-step explanation:
Answer:
2 sides are 38cm long
The third is 46cm long
Step-by-step explanation:
We can use the following equation to solve
Reduce
114÷3 = x
x = 38
We then add 38 and 8 because the 3rd side is 8cm longer
