Answer:

16x^{2}-24xy+ 9y^{2}

Step-by-step explanation:

To solve the squared binomial you just have to remember the formula:

(a+b)^{2} = a^{2}+ 2ab+b^{2}

So your equation would look like this:

(4x+3y)^{2}= (4x)^{2}+(2)(4x)(-3y)+(-3y)^{2}

So after doing the multyplications you are left with:

(4x+3y)^{2}= 16x^{2}-24xy+9y^{2}

That is you answer.

Answer:

16x^2-24xy+9y^2.

Step-by-step explanation:

Since this is in the form of (x-y)^2, we can plug it into x^2-2xy+y^2.

So, we get 16x^2-24xy+9y^2.

soldi70 [24.7K]

Answer:

\sqrt{549} ≈ 23.4

Step-by-step explanation:

A = bh

270 = 15b

b = 18

Now you know the two legs, use the Pythagorean Theorem to find the value of the hypotenuse:  a² + b² = c²

15² + 18² = c²

225 + 324 = c²

c² = 549

c = √549

Please help me with geometry! &lt;3<br> In rhombus ABCD, m&lt;=53*, What is M (*=degrees)
julia-pushkina [17]
In a rhombus opposite angles are equal and all 4 add up to 360
assuming one angle is 53, the opposite angle will also be 53 and then adjacent angles will be (360 - (53 x 2))/2 = 254/2 = 127*(deg)
I think the answer you're looking for is 127

Need help please would really be greatful
Rainbow [258]

Answer:

122°  

Step-by-step explanation:

The formula for finding the sum of all angles in a polygon is:

(n-2) * 180°

n is the number of angles

Here n = 7, so the sum of all angles is

(7-2) * 180°  = 900°

x = 900 - 128 - 130 - 120 - 115 - 145 - 140 = 122°

Make me the brainliest ;)
