Find the distance between P(-4,3) and Q(2,-5).

1 answer:

4 0

6,8 because it's the amount of numbers that it takes to get to the specific distance. You see for P,-4 and Q,2 the distance in between them is 6, because the amount that it takes for -4 to 2 is by counting up 6.

Help will give brainliest!!!!!

Answer:

at least three are dimes

so we have 20 coins with a total of 3.50

if the rest are all quarters then there would be 4*3+2=14 but we need 20

so we are 6 short

we must have dimes in multiples of 5

12 q + 5 d=3.50 but only 17 coins

10q +10 dimes=3.50 with 20 coins

10 q +13 dimes total

algebraic solution

d+q=23

25q+10d=380

d=23-q

I’m confused on this one

Ghella [55]

In a parallelogram, the opposite angles will be congruent to each other.

In this parallelogram, angles B and C are congruent, and angles A and D are congruent.

We will work on angles B and C first. Set the two angles to equal each other:

$12x + 6 = 6x + 66$

Subtract 6 from both sides:

$12x = 6x + 60$

Subtract 6x from both sides:

$6x = 60$

Divide both sides by 6 to get x by itself:

$\boxed{x = 10}$

x will equal 10.

Set angles A and D to equal each other:

$54 = 3y$

Divide both sides by 3 to get y by itself:

$\boxed{y = 18}$

y will equal 18.

The x and y values that make this quadrilateral a parallelogram will be x = 10, and y = 18.
