Answer:

10 x + 2 x^2

Step-by-step explanation:

Expand the following:

2 x (x + 5)

Hint: | Distribute 2 x over x + 5.

2 x (x + 5) = 2 x×5 + 2 x x:

2 x×5 + 2 x x

Hint: | Multiply 2 and 5 together.

2×5 = 10:

10 x + 2 x x

Hint: | Combine products of like terms.

2 x x = 2 x^2:

Answer: 10 x + 2 x^2

How do i solve this pls

First we would solve both x’s
3x^2 - 5x
But 3 has the thingy thing (forgot the name haha)
Which means you have to multiply it by itself that many times which would be
3x3=9
So now it would be
9x- 5x = 4x
Which leaves 7 and 4x

Now you may subtract those two

7-4x= 3x

-5x+4y=3 x=2y-15 Solve for y and x

serious [3.7K]

Answer:

x=9, y=12

Step-by-step explanation:

-5x+4y=3 --------A

x=2y-15----------B

Putting the value of x from B in A

-5(2y-15) +4y=3

-10y+75+4y=3

-6y=3-72

-6y=-72

y=72/6= 12

Putting the value of y =12 in B

x= 2(12)-15

x= 24-15

x=9
