If I understand correctly, you went wrong because you solved for Y instead of M, like the question dictates.
(x + 5) * (x − 5) =
x² - 25
----------------
x * x = x² and 5 * (-5) = -25
Answer:
B
Step-by-step explanation:
The volume (V) of a rectangular prism is calculated as
V = length × width × height
Calculate the volume of each prism
Q → V = 8 × 4 × 5 = 60 ft³
R → V = 6 × 7 × 12 = 504 ft³
S → V = 4 × 10 × 12 = 480 ft³
T → V = 2 × 13 × 5 = 130 ft³
Prism R has the greatest volume → B
Answer:
The value of x is 5
Step-by-step explanation:
In the given triangle
∵ A segment joining two points lie on the two side
∵ This segment is parallel to the third side
∴ This segment divides the two sides into parts that have the same ratio
→ That means x over 2x - 3 equal to 10 over 14
∵
= 
→ By using cross multiplication
∴ 10 × (2x - 3) = x × 14
∴ 10(2x) - 10(3) = 14x
∴ 20x - 30 = 14x
→ Add 30 to both sides
∵ 20x - 30 + 30 = 14x + 30
∴ 20x = 14x + 30
→ Subtract 14x from both sides
∵ 20x - 14x = 14x - 14x + 30
∴ 6x = 30
→ Divide both sides by 6
∴ x = 5
∴ The value of x is 5
Ok
1/9=1present
3hours=xpresent
1/9 times x=3
multiplyboth sides by 9
x=27
answer is 27
another way is
1/9 hour=1 present
1hour=9present
3 hour=27 present
