Answer: The answer is 2x + 7.
Explanation: First, we need to add the numbers:
9x + 3 – 7x + 4
9x + 7 - 7x
And finally, we combine like terms:
9x + 7 - 7x
2x + 7
2/10 because 0.7/7 is equal to one tenth, so 1.4/7 is equal to 2/10
Step-by-step explanation:
10x²+2x-8=0
=>10x²+10x-8x-8=0
=>10x(x+1)-8(x+1)=0
=>(10x-8)(x+1)=0
=>2(5x-4)(x+1)=0
Option B
Answer:
Step-by-step explanation:
3(x + 4) - 5 = 2x + 4
solve for x
x = -3
