Find the product of (2x + 5y)^2

netineya [11]

$(2x+5y)^{2}$ is (2x+5y)(2x+5y) so now you use FOIL (First, Outer, Inner, Last) to distribute.

$4x^{2}$ +10xy+10xy+ $25y^{2}$
Now combine like terms
$4 x^{2}+20xy+ 25y^{2}$

Hope that helps

1. Simplify -7 + {12 - 3[50 - 4(2+3)] }

Komok [63]

1. Simplify $-7 + (12 - 3[50 - 4(2+3)])$ this expression step by step:

$2+3=5;$
$4\cdot (2+3)=4\cdot 5=20;$
$50-4\cdot (2+3)=50-20=30;$
$3\cdot [50-4(2+3)]=3\cdot 30=90;$
$12-3\cdot[50-4(2+3)]=12-90=-78;$
$-7 + (12 - 3[50 - 4(2+3)])=-7+(-78)=-7-78=-85.$

2. Simplify the expression $\dfrac{1}{3} + 6\left(\dfrac{2}{3} - \dfrac{1}{6}\right)^2$ in the same way:

$\dfrac{2}{3}-\dfrac{1}{6}=\dfrac{2\cdot 2-1}{6}=\dfrac{3}{6}=\dfrac{1}{2}$
$\left(\dfrac{2}{3} - \dfrac{1}{6}\right)^2=\left(\dfrac{1}{2} \right)^2=\dfrac{1}{4}$
$\dfrac{1}{3} + 6\left(\dfrac{2}{3} - \dfrac{1}{6}\right)^2=\dfrac{1}{3} + 6\cdot \dfrac{1}{4}=\dfrac{1}{3}+\dfrac{3}{2}=\dfrac{1\cdot 2+3\cdot 3}{6}=\dfrac{11}{6}$

Let x and y be inversely related. If x is 5 when y<br> is 6, find y when x is 3.

scZoUnD [109]

Answer:

y=10

Step-by-step explanation:

x=k/y

constant of proportionality

k=xy

k=5*6

k=30

therefore x=30/y

if x=3 y=?

y=30/3

y= 10

Which expression is equivalent to 5(4x+3) - 2x

Troyanec [42]

Good evening

Answer:

18x + 15
3(6x + 5)

Step-by-step explanation:

Unfortunately you didn’t provide the expressions to chose from ,however we can get other expressions From this one like this:

5(4x+3) - 2x = 20x + 15 - 2x

= (20x - 2x) + 15

= 18x + 15

we can also write 18x + 15 = 3×(6x) + 3×(5x) = 3(6x + 5)

then

these two expressions :

18x + 15
3(6x + 5)

are equivalent to 5(4x+3) - 2x
