Answer:
I agree this is a horrible issue the answer is no she isn't great :(
Same thing happened to me in French just use word reference its really good for looking up single words ex. chair, blue, keyboard, paper, bed
Is was very useful in those hard times, anyway have a good day :)
Answer:
PR = 17 cm
Step-by-step explanation:
Given :
In ΔPQR,
PQ = 39 cm
PN is an altitude.
QN = 36 cm
RN = 8 cm.
To Find : Length of PR
Solution :
Since we are given that PN is an altitude .
So, PN divides ΔPQR in two right angled triangles named as ΔPQN and ΔPRN. (Refer attached file)
So, first we find Length of PN in ΔPQN using Pythagoras theorem i.e.
Thus, Length of PN = 15cm
Now to find length of PR we will use Pythagoras theorem in ΔPRN.
Hence the length of PR = 17 cm

The vertex form of y = 2x² - 12x + 25 is y = 2(x - 3)² + 7
Step-by-step explanation:
The vertex form of a quadratic function is y = a(x - h)² + k, where
- (h , k) are the coordinate of the vertex point
- a is the leading coefficient (coefficient of x²)
- If y = ax² + bx + c, then
- k = f(h) that means the value of y when x = h
∵ y = 2x² - 12x + 25
∵ y = ax² + bx + c
∴ a = 2 , b = -12 , c = 25
∵
∴
∴
∴ h = 3
∵ k = f(h)
∴ k = f(3)
∵ y = 2x² - 12x + 25
- Substitute x by 3 to find k
∴ k = 2(3)² - 12(3) + 25
∴ k = 18 - 36 + 25
∴ k = 7
∵ The vertex form is y = a(x - h)² + k
∵ a = 2 , h = 3 , k = 7
∴ y = 2(x - 3)² + 7
The vertex form of y = 2x² - 12x + 25 is y = 2(x - 3)² + 7

Step 1.) Distribute
-x + (-1)(13) + (-1)(4x)= (-3)(5) + (-3)(-9x) + 2
-x -13 -4x= -15 + 27x +2
Step 2.) Combind like terms
-5x -13= 27x -13
Step 3.) All the x's on one side
-13= 32x-13
Step 4.) Solve
x=0
