Answer:

(0.4x + 6y)^2

Step-by-step explanation:

Given

4.8xy+36y^2+0.16x^2

Required

Express as a binomial squared

4.8xy+36y^2+0.16x^2

Rewrite as:

0.16x^2+4.8xy+36y^2

Expand

0.16x^2 + 2.4xy + 2.4xy + 36y^2

Factorize:

0.4x(0.4x + 6y) + 6y(0.4x + 6y)

Factor out 0.4x + 6y

(0.4x + 6y)(0.4x + 6y)

Express as a square:

(0.4x + 6y)^2

Solve by substitution. Show each step of your work.<br><br> 2x + y = 7<br><br> 3x + 5y = 14
Monica [59]
Alright...simple...showing all steps.. ;)

You have the equations...

2x+y=7
and
3x+5y=14

To be able to even solve for any of the variables...multiply the equations by...2...and..3...

2x+y=7----*3--> 6x+3y=21
and
3x+5y=14-----*2--->6x+10y=28

Thus,

6x+3y=21
-
6x+10y=28

=========

-7y=-7

y=1

Now, plug y back into any of the original equations....we'll use 2x+y=7 in this case....

2x+(1)=7

2x+1=7
      -1  -1

2x=6

x=3

Thus, the point of intersection for these two equations is (3,1)

The sum of three numbers is 54. The third number is 6 more than the first. The second number is 2 times the third. What are the
77julia77 [94]

Answer:

9, 30, and 15.

Step-by-step explanation:

Let the three numbers be a, b, and c.

The sum of them is 54. So:

a+b+c=54

The third number is 6 more than the first. In other words, c=a+6.

The second number is twice the third. In other words, b=2c.

Let’s write the second number in terms of a. Since b=2c, this means that b=2(a+6).

Let’s substitute them into our equation. So:

a+2(a+6)+(a+6)=54

Solve for a. Distribute:

a+2a+12+a+6=54

Combine like terms:

4a+18=54

Subtract 18 from both sides:

4a=36

Hence, the value of a is:

a=9

So, the first number is 9.

The third number is 6 more than the first, so the third number is 15.

The second number is twice the third. So, the second number is 30.

Therefore, our numbers are:

9, 30, and 15.

Which equation could be used to solve this problem? The sum of two consecutive integers is 141. Find the integers. A. n + 1= 141
Kamila [148]
D. works because if you work it out that means 2n=140 and then divide by 2 which means n=70 and the other number is 71
