Answer:

5 * (n+3) = 4

n = -11/5

Step-by-step explanation:

5 * (n+3) = 4

Distribute

5n +15 =4

Subtract 15 from each side

5n +15-15 = 4-15

5n = -11

Divide by5

5n/5 = -11/5

n = -11/5

Solve for all values of x by factoring.<br> x^2 + 4x – 30 = -3x

vichka [17]

Answer:

${x}^{2} + 4x - 30 = - 3x \\{x}^{2} + 7x - 30 = 0 \\ {x}^{2} - 3x + 10x - 30 = 0 \\ x(x - 3) + 10(x - 3) = 0 \\ (x - 3)(x + 10) = 0 \\ \boxed{x = 3} \\ \boxed{x = - 10}$

<h3><em><u>x=3 or x=-10</u></em> is the right answer.</h3>

Find the distance between the two points～<br>A ( 7 , 4 ) and B ( 3 , 2 )<br><br><br>thankyou!

vodka [1.7K]

Answer:

AB = $\sqrt{20}$

Step-by-step explanation:

calculate the distance using the distance formula

d = $\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

with (x₁, y₁ ) = B (3, 2 ) and (x₂, y₂ ) = A (7, 4 )

AB = $\sqrt{(7-3)^2+(4-2)^2}$

= $\sqrt{4^2+2^2}$

= $\sqrt{16+4}$

= $\sqrt{20}$

≈ 4.47 ( to 2 dec. places )
