In the like terms column, the variables (the letters you see next to the numbers) are the same, and if they have an exponent the exponent is the same number too.

In the unlike terms column, they have different variables which means you can’t add or subtract them together. They also have different exponents, so you can’t add or subtract them either.

The coefficients can be different, but the variable and the degree of the variable must remain the same in order for it to be considered like terms. Hope this helped!

Can someone please explain why this is incorrect? Isn’t (2x+5)(x+1) the same as (x+1)(2x+5)?

Ne4ueva [31]

Answer:

2(2x+5) (x+1) = 2(x+1)(2x+5)

Step-by-step explanation:

4x^2 +14x+10

Factor out the 2

2(2x^2 +7x+5)

2(2x+5) (x+1)

You need to keep the 2 that you factored out

2(2x+5) (x+1) = 2(x+1)(2x+5) by the Commutative Property of Multiplication

A ball is thrown into the air. The height in feet of the ball can be modeled by the equation h = -16t2 + 20t + 6 where t is the

makkiz [27]

$f(t)=h=-16t^2+20t+6

$

a=-16, b=20, c =6

Δ= $b^2-4ac=20^2-4*(-16)*6=400+384=784$

$\sqrt{Δ}=\sqrt{784}=28$

max:

$p=-\frac{b}{2a}=-\frac{20}{-32}=\frac{20}{32}=\frac{5}{8}$

max heigh: $h=-16(\frac{5}{8})^2+20*\frac{5}{8}+6=-16\frac{25}{64}+\frac{100}{8}+6$

$h=-\frac{25}{4}+\frac{50}{4}+6=\frac{-25+50+24}{4}=\frac{49}{4}$

$h=\frac{49}{4}$ at $t=\frac{5}{8}s$

will fall down at t:

$t=\frac{-20-28}{-32}=\frac{-48}{-32}=\frac{3}{2}=1.5$

$t=1.5s$

What are three ways to get 256 using exponents

Nastasia [14]

recall from the previous posting, 2⁸ = 256, so that's one way to represent it.

now, another way hmmm

$\bf 2^8\implies 2^{2\cdot 4}\implies (2^2)^4\implies (4)^4\implies 4^4
\\\\\\
\stackrel{\textit{yet another way}}{2^8\implies 2^{4\cdot 2}}\implies (2^4)^2\implies (16)^2\implies 16^2$
