Answer:
16x^2+36x-10
Step-by-step explanation:
2 (4x - 1)(2x + 5)
=2(8x^2-2x+20x-5)
=2(8x^2+18x-5)
=16x^2+36x-10
Step 1) Find common denominator. In this case it was 28.
Step 2) Multiply 1/4 by seven to get 7/28 and then 2/7 by 4 to get 14/28.
Step 3) Add numerators: 7+14 to get 21
Step 4) Simpify your new added Fraction 21/28= 3/4
Your answer is 3/4

Answer:
Multiply the numerator and the denominator of the fraction by 2.
Step-by-step explanation:
Here are the options :
Divide the numerator and denominator of the fraction by 2.
Subtract 40 from the numerator and denominator of the fraction.
Multiply the numerator and the denominator of the fraction by 2.
Add 50 to the numerator and denominator of the fraction.
(45 x 2) / (50 x 2) = 90/100
Multiply 90/100 by 100 = 90%
the same answer would be gotten if 45/50 is multiplied by 100
45/50 x 100 = 90%
Answer:
x = 100°
Step-by-step explanation:
in the given figure
(x + 23°) + 57° = 180°
(they form linear pair)
- x + 23° + 57° = 180°
- x + 80° = 180°
- x = 180° - 80°
- x = 100°
3/12 is a rational number because rational numbers can be written in the form of a/b
When you simplify 3/12, you get 1/4, which is a fraction
