I hope you speak english, because although i understood your question I don't know enough spanish to respond in it. You multiply polynomials by multiplying each part of one polynomial by all the other parts of the others, and then adding it all. For example: (ax+b) * (x+c) = (ax*x)+(ax*c)+(b*x)+(b*c) =
Comprehende?
A.) We know, sum of the complimentary angles is equal to 90.
So, Equation: 15 + x = 90
B.) Solving: 15 + x = 90
x = 90 - 15
x = 75
In short, Your Answer would be 75
Hope this helps!
Answer: 45
Step-by-step explanation: I used a graphing calculator and input all the equations and all the restraints, and I found that you can’t use the first equation since x has to be less than or equal to -3, and the question calls for x to be -2. So, in the second equation, there’s a point (-2, 16) and in the third equation there’s a point (1, -3). You know you have to use these two points since in the second equation, the restraint only lets you use numbers greater than -3 or less than 0, which cannot be one, and in the third equation, the restraint only lets you use numbers greater than 0, which can’t be -2. I hope that made some sense. So then, with substitution the equation would be 3(16)+(-3) which equals 45. 3(16)=48. 48-3+=45
Answer:
3.33
Step-by-step explanation:
To solve for x you must divide both sides of the equation by 18. This is the DPE. Then the two 18s cancel each other out leaving u with x. Then divide 60 by 18 which then equals to 3.33. This Then gives the answer x=3.33.
