Step-by-step explanation:
The total of all angles in the triangle is 180
You already know 2 values for the triangle, Angle A 25 as well as Angle C 90
Your formula is
180 - 90 -25
Answer:
D=12yrs ANSWER 1: The daughter is 12 years old.
J=4D=4(12yrs)=48yrs ANSWER 2: Mr. James is 48 years old.
CHECK
J-D=36yrs
48yrs-12yrs=36yrs
36yrs=36yrs
Step-by-step explanation:
The expression given as x³ + 4x² - 3x + 1 cannot be factored
<h3>How to determine the factor the
expression?</h3>
From the question, we have the following expression that can be used in our computation:
x³ + 4x² - 3x + 1
The above expression is a polynomial expression
The number of terms in the expression is 4
This means that, when the terms are grouped in twos, we should be above to factor the expression
[x³ + 4x²] - [3x - 1]
However, this is not the case because [x³ + 4x²] and [3x - 1] or any other combination do not have common factor
So, it is better to leave the expression without changing its form
Hence. x³ + 4x² - 3x + 1 cannot be further factored

Answer:
y=-4x^2+9x+9
Step-by-step explanation:
1st: we assume the equation will be in standard form (ax^2+bx+c)
2nd: since the graph passes through (0,9) then the y-intercept is @(0,9) or your c is 9.
3rd: since it passes through (2,11) then 11=4a+2b+c
4th: since it also passes through (3,0) then 0=9a+3b+c
* so we have c=9, 11= 4a+2b+c, and 0= 9a+3b+c*
So a=-4, b=9, c=9
plug in the numbers and you get y= 4x^2+9x+9
Hope this helps you. :3
