Answer:
x = 12
y = 13
Step-by-step explanation:
Let's assume the two numbers as x and y.
The sum of the two numbers is 25
So,
The product of the two numbers is 156
- xy = 156
- x(25 - x) = 156
- 25x - x² = 156
- x² - 25x + 156 = 0
- x² - 13x - 12x - 156 = 0
- (x - 12) • (x - 13) = 0
- x - 13 = 0
- x = 13
- x - 12 = 0
- x = 12
Hence, the two numbers are 13 and 12.
Answer:
20 m
Step-by-step explanation:
Given that :
Scale of 1 : 50 is used to make a model
If the model has a height of 40 cm ; the height of the house is:
Then, the actual height of the house is (40 * 50) = 2000 cm
Thus the height of the house in metre is :
100cm = 1 meter
2000 cm = 2000 / 100
2000 cm = 20 meter
Height of house in meter = 20 meter
Answer:
I can't even see anything can you reupload your answer, please?
Step-by-step explanation:
SOH,CAH, TOA so it would be TANGENT since it would be Opposite over Adjacent. Tan(15) = 9/a put Tan(15) onto your calculator it would be .267949 round that to .27 = 9/a cross multiply
a = 33.588. C is the correct answer.
the answer is true because 6x multiply -2 to give -12x and 6x multiplies x² to give 6x³
