2. (a＋b)²＝a²＋2ab＋b²
(5x－2)²＝(5x)²－2×5x×2＋2²
(5x－2)²＝25x²－20x＋4
4. (a＋b)²＝a²＋2ab＋b²
(2x＋5)²＝(2x)²＋2×2x×5＋5²
(2x＋5)²＝4x²＋20x＋25
∵a＝4, b＝20, c＝25
∴a＋b＋c＝4＋20＋25＝49
Hope my answer helped u :)
Excluded values are any values of x that make the denominator equal zero. In this case, -2 and 2 are excluded values.
Answer: (0,1)
Step-by-step explanation:
If 
and 
are two point son a coordinate plane and (x,y) dividing it in a ratio of m: n.
Then , the coordinates of (x,y) is given by :-
Given : On a coordinate plane, a line is drawn from point A to point B. Point A is at (2, - 3) and point B is at (- 4, 9).
Then , the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2 :
Hence, the x- and y- coordinates of point E = (0,1)
The answer will be -8
hope this help!!!!!!!!!
Answer:
9r²(r - 8)
Step-by-step explanation:
Step 1: Write expression
9r³ - 72r²
Step 2: Factor out 9
9(r³ - 8r²)
Step 3: Factor out r²
9r²(r - 8)
