Answer:

- 8xy ^{2}  + 16x^{2}y

Step-by-step explanation:

if we put together the like terms (xy^2 and x^2y) then it would be

{6xy}^{2}  -  {14xy}^{2} +  {15x}^{2}y +  {x}^{2}y

then we combine the like terms which results in

- 8xy^{2}  +  {16x}^{2}y

HACTEHA [7]

Answer:

3.7%

Step-by-step explanation:

(p)principal=$3400

(t)time=9months=9÷12year=3÷4year

(i)interest=$94.50

(r)rate=?

we have

r%=i/(pt)

r%=94.50÷(3400×3÷4)

r÷100=94.50÷2550

r=0.37×100

r=3.7

required rate is 3/7%

The combined age of three relatives is 120 years. James is three times the age of Dan, and Paul is two times the sum of the ages
d1i1m1o1n [39]

Answer:

Step-by-step explanation:

From the problem statement, we can create the following equation:

J + P + D = 120

where J is the age of James, P is the age of Paul, and D is the age of Dan.

From the first part of the second sentence, we can set up the following equation:

J = 3D

From the last part of the second sentence, we can set up the following equation:

P = 2(J + D)

We can substitute the second equation into the last one to get the following:

P = 2(3D + D)

P = 2(4D)

P = 8D

We can then substitute the last two equations in the first to solve for D:

3D + 8D + D = 120

12D = 120

D = 10

Plugging this into the other two equations will give us the remaining ages:

P = 8D

P = 8(10)

P = 80

J = 3D

J = 3(10)

J = 30

Can you please solve a it is so important

F(x)=-x2+5n
g(x)=-2n+15
A(x)=|g(x)-f(x)|=|x2-7n+15|
x2-7n+15>0 for every x (1)
A(x)=x2-7n+15

(1):
x2-7n+15=(x-3.5)^2-12.25+15=(x-3.5)^2+2.75 > 0
because for every x: (x-3.5)^2>=0

answer: A(x)=x2-7n+15

a carton contains 1 3/4 quarts of ice cream. One serving is a 1/5 of a quart. How many servings are in the carton?
tatuchka [14]

Answer: 8 3/4

Explanation: Well in order to solve this equation, you must make the denominators equivalent. A common factor between 4 and 5 is 20. But since we multiplied the denominators, we have to do the same to the numerators. 3 x 5 = 15. 1 x 4 = 4. Our new fractions are now 1 15/20 and 4/20. Now that we have made our denominators equivalent, we can divide. 1 15/20 divided by 4/20 is 8 15/20. But we are not done yet, after we must simplify the fraction. Which would be 8 3/4.
