I dont know what to do lol

atroni [7]

Answer:

15 units

Step-by-step explanation:

The distance between two points can be found using the following formula:

$d\sf=\sqrt{(x_2-x_1)+(y_2-y_1)}$

Given points:

(-7, 5) and (2, -7)

where:

x₁ = -7
x₂ = 2
y₁ = 5
y₂ = -7

Substitute these points into the formula and simplify:

$\sf d=\sqrt{(2-(-7))^2+((-7)-5)^2} \ \textsf{[simplify the radicand]}\\\\ d=\sqrt{(2+7)^2+(-12)^2} \ \textsf{[simplify]}\\\\d=\sqrt{(9)^2+(-12)^2} \ \textsf{[evaluate the power]}\\\\d=\sqrt{81+144} \ \textsf{[add]}\\\\d=\sqrt{225}\ \textsf{[simplify]}\\\\d=15$

The distance between the two points is 15 units.

$(x-y)^2=x^2-2xy+y^2\\---------------------------\\\\4-12r+9r^2=2^2-2\cdot2\cdot3r+(3r)^2=(2-3r)^2$

$other\ method:\\\\4-12r+9r^2=4-6r-6r+9r^2=2(2-3r)-3r(2-3r)\\\\=(2-3r)(2-3r)=(2-3r)^2$

Can someone please help me with 7 and 8...thank you <3

Ivenika [448]

Answer:

Step-by-step explanation:

7. <A + [Since Co-interior angles]

=> 51° + <B = 180°

=> <B = 180° - 51°

=> 

8. <M + <N = 180°  [Since Co-interior angles]

=> 95° + <N = 180°

=> <N = 180° - 95°

=> <N = 85° (Ans)
