Answer:
They called the campaign "ABC"--Abstain, Be faithful, or, as a last resort, use a Condom. Within a few years, Uganda had developed what researchers call a "social vaccine" against HIV: cultural norms about sexual responsibility, preached in clinics and public schools, as well as churches and mosques.
Step-by-step explanation:
The ABC strategy is credited for bringing the HIV/AIDS epidemic under control in Uganda. By promoting abstinence, being faithful, and condom use, safe(r) behaviors have been identified that are applicable to people in different circumstances.
The answer to the question is b
Answer:
Factoring the expression
completely we get ![\mathbf{xy^4(x+1)(x^2-x+1)}](https://tex.z-dn.net/?f=%5Cmathbf%7Bxy%5E4%28x%2B1%29%28x%5E2-x%2B1%29%7D)
Step-by-step explanation:
We need to factor the expression
completely
We need to find common terms in the expression.
Looking at the expression, we get
is common in both terms, so we can write:
![xy^4+x^4y^4\\=xy^4(1+x^3)](https://tex.z-dn.net/?f=xy%5E4%2Bx%5E4y%5E4%5C%5C%3Dxy%5E4%281%2Bx%5E3%29)
So, taking out the common expression we get: ![xy^4(1+x^3)](https://tex.z-dn.net/?f=xy%5E4%281%2Bx%5E3%29)
Now, we can factor the term (1+x^3) or we can write (x^3+1) by using formula:
![a^3+b^3=(a+b)(a^2-ab+b^2)](https://tex.z-dn.net/?f=a%5E3%2Bb%5E3%3D%28a%2Bb%29%28a%5E2-ab%2Bb%5E2%29)
So, we get:
![xy^4(1+x^3)\\=xy^4(x^3+1)\\Applying\:the\:formula\;of\:a^3+b^3\\=xy^4(x+1)(x^2-x+1)](https://tex.z-dn.net/?f=xy%5E4%281%2Bx%5E3%29%5C%5C%3Dxy%5E4%28x%5E3%2B1%29%5C%5CApplying%5C%3Athe%5C%3Aformula%5C%3Bof%5C%3Aa%5E3%2Bb%5E3%5C%5C%3Dxy%5E4%28x%2B1%29%28x%5E2-x%2B1%29)
Therefor factoring the expression
completely we get ![\mathbf{xy^4(x+1)(x^2-x+1)}](https://tex.z-dn.net/?f=%5Cmathbf%7Bxy%5E4%28x%2B1%29%28x%5E2-x%2B1%29%7D)
Answer:
The answer is B. 12 cm
Step-by-step explanation:
ABC is a right triangle
AB and BC are the legs and AC is the hypotenuse.
The Pythagorean theorem a^2 + b^2 = c^2 can be manipulated to solve for a and get 12.
