Explain why x2 + 25 is not equal to (x + 5)2.
Step-by-step explanation:
Because in (x + 5)2 you have to multiply 2 by each term in the parentheses, and that is not equal to x2 + 25. itll be 2x + 10 and that is not equivalent.
x² + 25 is not equal to (x+5)² because the later has an extra term 10x in it.
What is a quadratic equation ?A quadratic equation has a highest degree of 2 and it has two solutions or roots which satisfies ax² + bx + c = 0.
According to the given explain why x² + 25 and (x+5)² are not equal.
We know (a+b)² = a² + 2ab + b².
So, (x+5)² = x² + 10x + 25.
On the other hand x² + 25 can be written as x² + 5².
∴ (x+5)² ≠ x² + 5².
There is an extra term 10x in (x+5)² or we can say x² + 25 is 10x less than (x+5)².

1. ∠B ≅ ∠P and BC ≅ PQ
2. ∠A ≅ ∠T and AC = TQ = 3.2cm
4. ∠A ≅ ∠T and BC ≅ PQ
Recall:
For two triangles to be congruent by AAS Congruence Theorem, they must have two pairs of congruent angles and a pair of non-included congruent side.For two triangles to be congruent by ASA Congruence Theorem, they must have two pairs of congruent angles and a pair of included congruent side.We are given:

They're just hired a new employee to work in your bike shop in one hour the employee burns 55 chocolate chip cookies if this represented 22% of the days production how many cookies did you plan on producing that day
Answer:
250 cookies
Step-by-step explanation:
The employee burns 55 chocolate chip cookies
if this represented 22% of the days production
Let x = the total production of cookies for the day
how many cookies did you plan on producing that day?
22% of x = 55
22 / 100 * x = 55
0.22x = 55
Divide both sides by 0.22
x = 55 / 0.22
= 250
x = 250 cookies
Therefore, the total production of cookies for the day is 250

-MY REAPORT CARD IS COMING SOON AND I HAVE ALL F'S my mom snitches and would tell everyone like she did last time so before my mom get's it should I
A. run away from home
B. Break her phone
C. blackmail her, when she DOES get it
*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*
♡ The Answer ♡
- None of the Above!
*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*
♡ The Explanation/Step-By-Step ♡
- A would not be a very good idea, running away from home can get you in trouble either from your parents/family/guardians, or police/fire department, that would most likely upset your mother more and could cause some issues. B wouldn't be good because soon enough she will most likely find out, breaking somebody's phone can be a bad idea too, if they're in danger they won't be able to call anybody or ask for any help. Including something important could be saved there, not to mention phones are very expensive and it could be devastating.
C isn't much of a better idea either, blackmailing somebody isn't something to be proud of and if anything, is very risky. Blackmailing is demanding money from somebody in return for not revealing compromising info about the person you're threatening. This may only be reputation ruining, but not to mention if the police/fire department find out you're threatening somebody for money you could most likely get arrested.

help me its an algebra 2 question 2. John can mow his lawn in 3 hours and his sister, Julie, can mow it in 2 hours. How long will it take them to mow their lawn if they work together?
A. 1 hour 12 minutes
B. 1 hour 15 minutes
C. 1 hour 20 minutes
D. 1 hour 30 minutes
E. 1 hour 35 minutes
Answer:
A
Step-by-step explanation:
John can mow the same lawn in 3 hours.
In 1 hour he can mow 1/3rd of the lawn.
In 1 hour they can together mow (1/2+1/3)=5/6th of the lawn.
Together they can mow the lawn in 6/5 hours=1.2 hours.
I hope this helped, please mark Brainliest, thank you!!
Time taken to mow the lawn together is 6/5 hours i.e., 1.2 hours.
The correct option is (C).
What is a algebra ?Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols.
Given:
John can mow his lawn in 3 hours.
Julie can mow same lawn in 2 hours.
In 1 hour = 1/3rd of the lawn.
In 1 hour, together they can mow
= (1/2+1/3)
=5/6th of the lawn.
Hence, time taken to mow the lawn together is 6/5 hours i.e., 1.2 hours.
