4x-2y=12 -4x-9=54 How can you order a ladder?

Mathematics
1 answer:
blagie [28]3 years ago
3 0
Equations:

4x - 2y = 12
-4x - 9y = 54

Multiple them in both sides

4x - 2y - 4x - 9y = 12 + 54
-2y - 9y = 66
-11y = 66
y= -6

If y= -6 then put y in first or second equation.

I put it in first equation

4x - 2.(-6) = 12
4x + 12 = 12
x= 0

Therefore

(x,y) = (0, -6)

Answer:

\huge\boxed{\sf 46}

Step-by-step explanation:

<u>Formula for area of rectangle:</u>

= length × width

<u>Area of the smaller rectangle:</u>

length = 7

width = 6

= 7 × 6

= 42

<u>Area of the larger rectangle:</u>

length = 7 + 4 = 11

width = 6 + 2 = 8

= 11 × 8

= 88

<u>Area of the shaded region:</u>

= Area of the larger rectangle - Area of the smaller rectangle

= 88 - 42

= 46

\rule[225]{225}{2}

Hope this helped!
