Answer:
Replace all occurrences of +− with a single −. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1⋅−1 = −1
Y=x²−10, Y=2x−4
Eliminate the equal sides of each equation and combine.
x²−10 = 2x−4
Solve x²−10 = 2x−4 for x.
x= 1+√7, 1−√7
Evaluate Y when x = 1 + √7.
Y =−2 + 2√7
Evaluate Y when x = 1 − √7.
Y=−2 − 2√7
The solution to the system is the complete set of ordered pairs that are valid solutions.
(1+√7,−2+2√7)
(1−√7,−2−2√7)
The result can be shown in multiple forms.
Point Form:
(1+√7, −2+2√7), (1−√7, −2−2√7)
Equation Form:
x= 1+√7, y= −2+2√7
x= 1−√7, y= −2−2√7

Answer:
The length of the pother piece of the wood is 25 cm.
Step-by-step explanation:
Let the length of a piece of wood is x such that the ratio of two pieces is 2:5. Two pieces are 2x and 5 x
Length of the first piece is 10 cm. It means, 2x = 10 i.e. x = 5
We have considered that the length of other piece is 5x. It means 5×5 = 25 cm.
Hence, the length of the pother piece of the wood is 25 cm
