Answer: x2+17x+3
Step-by-step explanation:
2x2+7x−x2+10x+3
=2x2+7x+−x2+10x+3
Combine Like Terms:
=2x2+7x+−x2+10x+3
=(2x2+−x2)+(7x+10x)+(3)
=x2+17x+3
I think you would add all the glasses together which you would then get 89 then you would divide that number by two because we are looking for how much glasses Tina and Kate could both get so 89/2 =44.5 so they would each evenly get 44.5 glasses. I'm sorry I think this is what you were looking for?
0.4 is
and that simplified is
because you take the GCF or Greatest Common Factor, which is two, and divide both parts of the fraction taking
and turning it into
6x+3=45
6x+3-3=45-3
6x= 42
Divide by 6 for 6x and 42
6x/6= 42/6
x= 7
Check answer by using substitution method
6x+3= 45
6(7)+3= 45
42+3= 45
45= 45
The answer is x= 7
5:4 = 10:8 = length:width
10+8=18
162÷18= 9
9×10= 90
the length of the rectangle is D. 90 ft
