The only right answers is c... a would be 1/4 i don’t know what b would be, and d wouldn’t be right, it would have to be c
Answer:
1. (x +1)(x - 1)
2. (x+5)(x-5)
3. (x+12)(x-12)
4. (x+14)(x-14)
5. (x+5)(x-7)
Step-by-step explanation:
The first 4 expressions can be factored with the difference of squares type of factoring.
For #5, the odd one out is (x+5)(x-7) because it isn't a factor of any of the standard form equations, while the others are
Answer:
<h2>x=11/2</h2>
Step-by-step explanation:
solution
We going to do this process in a stepwise manner
given the expression
18=6(2x – 8)
1. open bracket on the left-hand side (distributive property)
18=12x-48
2. collect like terms
18+48=12x
66=12x
3. divide both sides by 12 we have
x= 66/12
x= 33/6
x=11/2
The answer is B) n+6. Simply because penny is 6 inches taller than Claire, which means you would have to add 6 inches to Claire's height to reveal penny's height. Also n represents Claire height which makes the expression easier to figure out.
We need to simplify it as there is no definite answer without knowing the value of <em>x. </em><span><span><span>2.5x</span>+<span>0.1x</span></span>−<span>0.01x</span></span><span>=<span><span><span><span>2.5x</span>+<span>0.1x</span></span>+</span>−<span>0.01x </span></span></span>Find the like terms:<span>=<span><span><span>2.5x</span>+<span>0.1x</span></span>+<span>−<span>0.01x
All of them have <em>x</em>, so they can be combined.
</span></span></span></span><span>=<span>(<span><span><span>2.5x</span>+<span>0.1x</span></span>+<span>−<span>0.01x</span></span></span>)
</span></span><span>=<span>2.59<span>x</span></span></span>
