Answer:
D. 7x - 6 = x + 6(x + 5)
Step-by-step explanation:
a equation will have no solution if the final value is not real or not equal
D) 7x - 6 = x + 6(x + 5)
7x-6 = x+6x+30
7x-x-6x-6-30= 0
-36≠0
so -36 ≠ 0 ... so no solution
A. 9x + 9 = 11x – 2x + 9
9x-11x+2x+9-9=0
0=0
have solution, Real, true
B. 7x + 30 = x + 6(x + 5)
7x+30 = x+6x+30
7x-x-6x+30-30= 0
0=0
have solution, Real, true
C. -5x + 9 = 2x + 9 - 7x
-5x-2x+7x+9-9= 0
-7x+7x=0
0=0
have solution, Real, true
Maybe it’s uhh uhhh 20 feet yuh
Answer:
iiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii
Step-by-step explanation:
To answer this question, you need to know that a quarter is worth $0.25 and dimes worth $0.10. In this case, the total number of money that made from quarters and dimes is $2.80
With Q=quarter and D=dime, then the equation should be:
2.80= 0.25 Q + 0.10 D
The condition that needs to be fulfilled in this case is that the quarter should be 8 more than dimes. Then you need to find out the highest possible number of the quarter and lowest possible number of the dimes.
If you divide 2.8 with 0.25 you will found it will be 11.2 but 11 quarter will result with 0.05 value which you cannot remove, so the highest possible of the quarter should be 10.
If the highest possible of the quarter is 10, then the lowest possible of dimes should be:
2.8= 0.25(10) + 0.10D
0.10D= 0.3
D=3
Since 10-3 is 7, then it is not possible for the quarter to be 8 more than the dimes.
The area of a rectangle is it's length times it's height. We are given polynomials for these values, so we can multiply them using the FOIL method to find the area.
FOIL stands for Firsts, Outers, Inners, Lasts. This means we multiply the first term of each polynomial together, the outer terms together, the inner terms together, and the last terms together.
(2x+5)(x-2)
The first terms are 2x and x, the outer terms are 2x and -2, the inner terms are 5 and x, and the last terms are 5 and -2:
2x^2 - 4x +5x - 10
Combine like terms:
2x^2 + x - 10
The third option is the correct answer.
