The answer = 3x^4+13x^3+20x^2+24x
Answer:
120 degrees so answer b
Step-by-step explanation:
the opposite angles in the shape are equal so <klm = <kjm. this means the answer is the same as the sum of the other sides so 78 + 42 which is 120 degrees
Answer:
I do not know what the rest of the problem is so I can not answer
Answer: x=-10
Step-by-step explanation:
Let's solve your equation step-by-step.
6.2x+8=3(1.4x−4)
Step 1: Simplify both sides of the equation.
6.2x+8=3(1.4x−4)
6.2x+8=(3)(1.4x)+(3)(−4)(Distribute)
6.2x+8=4.2x+−12
6.2x+8=4.2x−12
Step 2: Subtract 4.2x from both sides.
6.2x+8−4.2x=4.2x−12−4.2x
2x+8=−12
Step 3: Subtract 8 from both sides.
2x+8−8=−12−8
2x=−20
Step 4: Divide both sides by 2.
2x2=−202
