Answer: C, D
Explanation:
16 x 16 x 18 = 4,608
12 x 15 x 24 = 4,320
14 x 18 x 20 = 5,040
8 x 20 x 27 = 4,320
Answer:
13 , 17 and 25 cm.
Step-by-step explanation:
Let the length of the first side be x cm.
Then the second is x+4 and the third is 2x-1 cm long.
As the perimeter = 55 cm we have the equation:
x + x + 4 + 2x - 1 = 55
4x + 3 = 55
4x = 52
x = 13 cm.
Answer:
70/9
Step-by-step explanation:
Let's solve your equation step-by-step.
4−138=6(1−3x)
Step 1: Simplify both sides of the equation.
4−138=6(1−3x)
4+−138=(6)(1)+(6)(−3x)(Distribute)
4+−138=6+−18x
(4+−138)=−18x+6(Combine Like Terms)
−134=−18x+6
−134=−18x+6
Step 2: Flip the equation.
−18x+6=−134
Step 3: Subtract 6 from both sides.
−18x+6−6=−134−6
−18x=−140
Step 4: Divide both sides by -18.
−18x/-18=−140/-18
x=70/9
