23 is less than 25 which means it's closer to 20, so you would round it down to 20. 1.75 is over 0.50, 1/2, so you would round it up to 2. If you multiply 2 and 20 you would get 40.
Number two gets the same explanation just with different numbers.
Answer:
y = -2x + 5
Step-by-step explanation:
Given:
Passes through point (1, 3)
Perpendicular to x – 2y = -8
Solve:
x – 2y = -8
y = 1/2x + 4
The slope is m = 1/2
The slope of the perpendicular line is the inverse of the slope of the original equation.
The slope of the inverse equation is m = -2.
Making an inverse equation of y = -2x + a
Find a:
Use point, (1, 3) where (x, y):
3 = (-2)*(1) + a
a = 5
y = -2x + 5
A ratio of 11x to 10x
Where x is a number to keep the ratio the same.
Perimeter = 84
Perimeter = 2 (Length + breadth)
84 = 2 ( 11x + 10x)
84 = 2(21x)
21x = 42
x=2
So that means the actual length of the sides would be:
11 x 2 : 10 x 2
22 : 20
So that means the length can be 22, and the breadth will be 20.
Or the length is 20, and the breadth is 22.
The answer is c). (x-5)(x-7)
