-(2x+5)=-10-2x plz help

Scilla [17]

−(2x+5)=−10−2x

Step 1: Simplify both sides of the equation.

−(2x+5)=−10−2x

−2x+−5=−10+−2x(Distribute)

−2x−5=−2x−10

Step 2: Add 2x to both sides.

−2x−5+2x=−2x−10+2x

−5=−10

Step 3: Add 5 to both sides.

−5+5=−10+5

0=−5

There are no solutions.

What is the approximate distance between the points (-5,1) and (-2,3) on a coordinate grid? Show me an example please

yaroslaw [1]

Answer:

$d=\sqrt{13}\ units$ or $d=3.61\ units$

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

$A(-5,1)\\E(-2,3)$

substitute the values

$d=\sqrt{(3-1)^{2}+(-2+5)^{2}}$

$d=\sqrt{(2)^{2}+(3)^{2}}$

$d=\sqrt{13}\ units$

$d=3.61\ units$

Help for 10 points please

Westkost [7]

When using distributive property for this it’s gonna be 5(5.75+4.25)
So 5•5.75=28.75
5•4.25=21.25
So then 28.75+21.25=50
