If you round 23.19 to the nearest whole number you get 23 and if you round 13.7 you get 13. 13+23 is 33. The real numbers are 23.19 and 13.7, add them together and you get 36.89. The exact sum is 36.89 (:
B)(x+10).(x-6)=x²-6x+10x-60
x²+4x-60
C)(x+15).(x-4)=x²-4x+15x-60
x²+11x-60
D)(x+20).(x-3)=x²-3x+20x-60
x²+17x-60
But A,
(x+12)(x-5)=x²-5x+12x-60
x²+7x-60
A, is the correct answer..
GOOD LUCK!
Equivalent Ratios. Students learn to find equal ratios by first writing the given ratio as a fraction, then multiplying the numerator and denominator of the fraction by the same number. For example, to find two ratios that are equal to 1:7, first write 1:7 as the fraction 1/7. I hope this helps
Answer:
( 3x + 5 ) ( x - 4 )
Step-by-step explanation:
1.) Factors of 20 = (1,20) (2,10) and (4,5)
2.) ( 3x + 5 ) ( x - 4 )
3.) 3x - 12x + 5x - 20 = 0
4.) 3x^2 + 7x - 20 = 0
