The first one A) :)))))))
X time 0.8 (or 80 percent)= 15
so 15/0.8=X
18.75
Answer:
A
Step-by-step explanation:
The side lengths must satisfy the Pythagorean Theorem to be a right triangle. The formula is
where a is the smallest side, b is the medium side, and c is the largest side. Test each set of numbers.
![a = 6, b = 8, c= 10\\6^2 + 8^2 = 10^2\\36 + 64 = 100\\100 = 100](https://tex.z-dn.net/?f=a%20%3D%206%2C%20b%20%3D%208%2C%20c%3D%2010%5C%5C6%5E2%20%2B%208%5E2%20%3D%2010%5E2%5C%5C36%20%2B%2064%20%3D%20100%5C%5C100%20%3D%20100)
This satisfies the theorem. Since this is a multiple choice question, only one solution is possible. A is the solution.
The simplified expression of the provided equation in standard form is -2p²-11p-35. Option 1 is the correct option.
<h3>What is the simplified form of an expression?</h3>
Simplified form of an expression is the simplest way of expression the term, by applying the required operations of mathematics.
The expression which is need to be simplified is,
![-2(p +4)^2 - 3 +5p](https://tex.z-dn.net/?f=-2%28p%20%2B4%29%5E2%20-%203%20%2B5p)
First of all, open the brackets, using the formula of whole square,
![-2(p^2 +16+8p) - 3 +5p\\-2p^2-32-16p-3+5p\\-2p^2-11p-35](https://tex.z-dn.net/?f=-2%28p%5E2%20%2B16%2B8p%29%20-%203%20%2B5p%5C%5C-2p%5E2-32-16p-3%2B5p%5C%5C-2p%5E2-11p-35)
Hence, the simplified expression of the provided equation in standard form is -2p²-11p-35. Option 1 is the correct option.
