Answer:
-113
Step-by-step explanation:
2a^4+5b^3 --> 2(4)^4+5(-5)^3= -113
not 100% on this since its hard to understand the original equation (I'm assuming that the numbers after the variables are exponents)
The length of the side is 7 because you have to multiply the length and the width together to get the area. 7x7=49

Hello,
First of all, relax and take a deep breath right before you start.
Alright, so algebraic word problems are tricky sometimes. I am glad I don’t have to do them much. Once you understand more or less what to do, you should be fine!
I would need an example problem if you have one.
If not, then remember that you have to work with what you know, which is what you can start with and what you need to end with.
For instance, a phone company sells phones at $900 each. For a family discount, after 2 phones are bought, each additional phone is $100 off.
Find an expression representing the phone company’s prices.
2*900 + (900x - 100x)
x represents how many additional phones were bought.
If a family bought 6 phones:
2*900 + (900x - 100x)
2 in front and 4 as x gives 6
That expression becomes
2*900 + [900(4) - 100(4)]
= $5000
I hope that helped!
