Answer:

We divide it into 3 rectangles:

A rectangle with sides 19mi and 5mi,

a rectangle with sides 1mi and 31mi,

and a rectangle with sides 10mi and 20mi,

so we get 95 + 31 + 200 = $\boxed{326}$

Hope this helps!

triangle hij had a vertices of h (1,7),I(-4,-2),j(-3,5) write the coordinate notation for a translation of 3 units to the right

yanalaym [24]

The coordinates are H'(4,11), I'(-1,2), J' (0,9).

Step-by-step explanation:

Triangle HIJ had a vertices of h(1,7), i(-4,-2), j(-3,5)

Here we are going to translate the pre-image.

Translation up means we have to add the translated units to the y-coordinate of the (x,y) point of the preimage.

Translation to the right means we have to add the translated units to the x-coordinate of the (x,y) point of the preimage.

So the points of the image have the change in points using the translation as,

(x+3, y+4)

So the points of the triangle may be changed as,

H (1,7) → H'(1+3, 7+4) → H'(4,11)

I (-4,-2) → I' (-1,2)

J (-3,5) → J' (0,9)

[Geometry Basics] I'm just checking if this is correct:

Hello there, and thank you for posting your question here on brainly.

Short answer: x = -5

Why?

The solution to this has a lot of steps. Subtract two from both sides. (2+7/x=3/5 --> 7/x=-7/5) Multiply both sides by x. (7/x=-7/5 --> 7=-7x/5) Multiply both sides by 5. (7=-7x/5 --> 35=-7x) Divide both sides by -7. (-5=x) x = -5

Hope this helped you! ♥

This is because 4x4 is 16, but it can’t be 3 since 4x3 is only 12.
