Show your work

Answer 6

To find the sum of 4x^10 and 9x^10, add the coefficient of the like terms:

4x^10 + 9x^10 = (4 + 9)x^10 = 13x^10

Therefore, the sum of 4x^10 and 9x^10 is 13x^10.

What If I Think I'm Pregnant
What is a sexually transmitted infection (STI)?
Can I tell if my partner has an STI just by looking at them?
Is this normal?

Answer 14

Sure, here are some brief answers to your questions about sex ed:

1. What is sexual health?
Sexual health refers to the physical, emotional, mental, and social well-being in relation to sexuality and sexual activity. It involves having access to accurate information and resources to make informed decisions about sexual behavior and relationships.

2. How do I know if I'm ready for sex?
Knowing if you're ready for sex is a personal decision that differs for each individual. It's important to consider factors such as physical readiness, emotional maturity, and communication with your partner. It's also important to practice safe sex by using contraception and getting regular testing for sexually transmitted infections (STIs).

3. What if I think I'm pregnant?
If you suspect you may be pregnant, it's important to take a pregnancy test and visit a healthcare provider to confirm the pregnancy and receive prenatal care.

4. What is a sexually transmitted infection (STI)?
A sexually transmitted infection (STI) is an infection that is transmitted through sexual contact. STIs can be caused by bacteria, viruses, or parasites, and can cause a range of symptoms including discharge, pain, and itching. Some STIs can also lead to long-term health problems if left untreated.

5. Can I tell if my partner has an STI just by looking at them?
It's not possible to tell if someone has an STI just by looking at them. Many STIs have no visible symptoms, and individuals can transmit the infection even without showing any signs. It's important to practice safe sex and get regular STI testing and treatment.

6. Is this normal?
It's normal to have questions and concerns about sexual health and to seek out information and resources. It's important to talk to a trusted healthcare provider or sexual health educator if you have any questions or concerns.

Answer 15

okay my next question is How long can a man ejaculate?

Answer 16

The duration of a man's ejaculation can vary and is considered normal as long as it takes longer than a few seconds. On average, ejaculations can last anywhere from a few seconds to around 10 seconds. However, there are individual differences and some men may experience longer or shorter durations. It's important to note that there is no set time for how long ejaculation should last and what is most important is that both partners are comfortable and enjoying their sexual experience.

Answer 17

Next one... How Do I use a condom?

Answer 18

Here are the steps on how to use a condom:

1. Before beginning sexual activity, check the expiration date of the condom and make sure the packaging has not been damaged.

2. Carefully open the package, being sure not to tear the condom with nails or any other sharp objects.

3. Pinch the tip of the condom to leave space for semen and roll it down the shaft of the erect penis.

4. Continue unrolling the condom down the entire length of the penis, making sure there are no twists or tears.

5. After ejaculation and before your penis becomes soft, hold the base of the condom and carefully remove your penis, being careful not to let it slip off inside your partner.

6. Wrap the used condom in tissue or paper and throw it away in the garbage. Do not flush condoms down the toilet.

It's important to remember to use a new condom for each sexual act and to store condoms in a cool, dry place away from direct sunlight. Protective barriers like condoms are effective in preventing unintended pregnancy and transmission of sexually transmitted infections.
