Answer: Which of the following expressions cannot be factored? Explain.
a. 6 + 3x
b. 7x + 3
c. 15x + 10
d. 30x + 40
Step-by-step explanation:
Hello,
Let's say there are n sides
(Put 2 in commun factor)
Perimeter is doubled.
3) Missing in 3): ∠EDF and ∠ADC = "Vertical angles"
Calculate x°:
∠ EDF = 120°
∠ EDF = ∠ ADC (Vertical) , but ∠ ADC = 3x° + 2x°,
Then 3x°+2x° =120°
5x° = 120° and x° =120/5, so x° =24°
Answer:
1. 6x + 25
2. 60 + 28k
3. 5 + 19y
4. 3d + 1
5. 5v
6. w - 14.04
Step-by-step explanation:
These are what I got. I'm very sorry if I'm wrong.
Answer:
a. -24
Step-by-step explanation:
Multiply by 6 ...
2/3(1/2x+12)=1/2(1/3x+14)-3
4(1/2x +12) = 3(1/3x +14) -18 . . . . . . multiply by 6
2x +48 = x +42 -18 . . . . . . . . . . . . . .eliminate parentheses
x = 24 -48 = -24 . . . . . . . . . . . . . . . . simplify and subtract (x+48)
