Naddik [55]

Answer:

$4 {x}^{2} + 2xy - 2 {y}^{2}$

Step-by-step explanation:

$(x + y)(x - 5y) + {3(x + y)}^{2} \\ x(x - 5y) + y(x - 5y) + 3(x + y)(x + y) \\ {x}^{2} - 5xy + xy - 5 {y}^{2} + (3x + 3y)(x + y) \\ {x}^{2} - 4xy - 5 {y}^{2} + 3x(x + y) + 3y(x + y) \\ {x}^{2} - 4xy - 5 {y}^{2} + 3 {x}^{2} + 3xy + 3xy + 3 {y}^{2} \\ {x}^{2} - 4xy - 5 {y}^{2} + 3 {x}^{2} + 6xy + 3 {y}^{2} \\ {x}^{2} + 3 {x}^{2} - 4xy + 6xy - 5 {y}^{2} + 3 {y}^{2} \\ 4 {x}^{2} + 2xy - 2 {y}^{2}$

Mary can build 2 sand castles ( c ) in 4 hours ( t ). Write an equation in the form of c=rt that represents the relationship bet

wariber [46]

2 = r(4)
To find r, you've gotta divide it out.
2/4 = r/4
1/2 or 0.5 = r

c=(0.5)t

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:

$P = 8D$

$P = 8(10)$

$P = 80$

$J = 3D$

$J = 3(10)$

$J = 30$

If DGH ~ DEF, Find the value of X

DIA [1.3K]

Answer:

$x=25$

Step-by-step explanation:

we know that

DGH ~ DEF ---> given problem

Remember that

If two triangles are similar, then the rtio of its corresponding sides is proportional and its corresponding angles are congruent

so

$\frac{DG}{DE}=\frac{GH}{EF}$

substitute the given values

$\frac{52}{91}=\frac{x+3}{2x-1}$

$(2x-1)52=(x+3)91\\104x-52=91x+273\\104x-91x=273+52\\13x=325\\x=25$
