Answer:
P22039
Step-by-step explanation:
Cost of new television = 29078
Let the price of old model television = x
2x - 15000 = 29078
2x = 29078 + 15000
2x = 44078
2x/2 = 44078 /2
x = 22039
Hence, price of old model television is P22039
Answer:
feet/million year
Step-by-step explanation:
We are given that
Elevation of top of basalt in valley =4100 feet
Elevation of bottom of basalt in valley =2100 feet
Age of top of basalt in valley=15000 years
Age of bottom of basalt in valley=1.2 million years=
We have to find the rate of basalt filling in the valley in feet per million yeas
Rate of basalt filling in the valley=
Rate of basalt filling in the valley=
Rate of basalt filling in the valley=
feet/million year
Answer:
Final result :
5y2
Reformatting the input :
Changes made to your input should not affect the solution:
(1): "y2" was replaced by "y^2". 1 more similar replacement(s).
Step by step solution :
Step 1 :
Trying to factor as a Difference of Squares :
1.1 Factoring: x-y2
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : x1 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares
Equation at the end of step 1 :
(2x + (3 • (y2))) - 2 • (x - y2)
Step 2 :
Equation at the end of step 2 :
(2x + 3y2) - 2 • (x - y2)
Step 3 :
Final result :
5y2
