Answer:
x = 18
Step-by-step explanation:
We need to find the value of x.
We know that the sum of angles of a triangle is equal to 180°. So, using this property,
2x+1+3x-1+90 = 180
2x+3x = 180-90
5x = 90
x = 18
So, the value of x is equal to 18.

Answer:
The answer is 743.4 square inches
Step-by-step explanation:
1. find the length- 2 x 40=80 cm
2. find the width- 1.5 x 40= 60cm
3. find area (Length x width)- 80 x 60= 4800 square cm
4. find length but in inches- 1in=2.54cm length=80/2.54 = 31.5 inches
5. find width but in inches- width= 60/2.54= 23.6 inches
6. Find area(length x width)- 31.5 x 23.6= 743.4 square inches
Solve for y. Do that by adding the opposite of the x-term, then dividing by the coefficient of y.
11y = 12x - 8
y = (12/11)x - 8/11
The slope is 12/11.
The y-intercept is -8/11.
