Answer:
2 ( 2a + 3b - 4)
Putting the value of a= 2 and b = 3 in the equation
2( 2(2) + 3(3) -4)
2 (4 + 9 -4)
2( 4 -4 + 9)
2 (0 + 9)
2 (9)
2 × 9

Step-by-step explanation:
I would write it but I have homework too
Answer:
Step-by-step explanation:
y = mx + b is the formula for slope intercept. What we can do is plug in the slope and coordinate points to find the y-intercept.
4 = (3) + b
-2/3 times 3 is -2 so you can fill that in place.
4 = -2 + b
<u>+2 +2 </u>
6 = b
So the y-intercept is 6 now we can complete the equation.
Hope that helps and have a great day!
Let the dimensions be x and y
Given that the area is 40m²
xy = 40 ----------------- (1)
Given that the perimeter is 26
2(x + y) = 26
x + y = 13
x = 13 - y ---------------- Sub into (1)
(13 - y)y = 40
13y - y² = 40
y² - 13y + 40 = 0
(y - 8)(y - 5) = =
y = 8 or y = 5
The dimensions are 8 meters and 5 meters
