Answer:

x = 42.9 m

Step-by-step explanation:

Corresponding sides of similar triangles MAB and MNP are proportional. This means ...

x/MP = MA/MN

However, we don't have a number for MA yet, so we need to find it.

MA +AN = MN

MA = MN - AN subtract AN

MA = 67.2 m - 32 m = 35.2 m

Now, we can use this to find x.

x = MP · (MA/MN) = (81.9 m) · 35.2/67.2

x = 42.9 m

Let A = -4k+ 3 and B = 3k +17. If A = B, then what is the value of k?

kupik [55]

Answer:

k=-2

Step-by-step explanation:

Using substitution to find what you're missing, (in this case k) is when you plug each letter into the other equation:

-4k+3=3k+17

So now solve for k:

subtract 3 from both sides...

-4k=3k+14

subtract 3k from both sides to combine with -4k...

-7k=14

divide -7 from both sides...

k=-2

Plz help ill give u brainlist

Area of the front and back faces = 2 [ (8.1 x 8.1) + (1/2 x 8.1 x 2.1 ] = 148.23 in²

Area of the right and left faces = 2 [ 11.8 x 8.1 ] = 191.16 in²

Area of the top = 2 [4.6 x 11.8] = 108.56 in²

Total Area = 148.23 in² + 191.16 in² + 108.56 in² = 447.95 in²

Answer: Theo will need to paint about 447.95 in².

I believe that it is C, mind you I could’ve got it wrong. It’s been awhile since I’ve done that kind of math.
