Answer:
Length = 4 inches
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
If x = 2
Perimeter = 8x - 4
= 8(2) - 4
= 16 - 4
= 12 inches
Width = 3x - 4
= 3(2) - 4
= 6 - 4
= 2 inches
Perimeter of a rectangle = 2(length + width)
12 = 2(length + 2)
12 = 2length + 4
12 - 4 = 2 length
8 = 2 length
Length = 8/2
Length = 4 inches
<h3>
Answer: 300 square feet</h3>
Explanation:
The trapezoid has area of
A = h*(b1+b2)/2
A = 6*(10+18)/2
A = 84
The rectangle is 18 ft by 12 ft, which leads to an area of 18*12 = 216 sq ft.
Adding the two sub-areas gets us: 84+216 = 300
The total area of the house-shaped figure is 300 sq ft.
You substitute the equation and see if it works. Also, the first one that you answered is wrong.
A is 3 (5) + 4 (0)>24 this is false because 3 times 5 equals 15 plus 4 time 0 which is 0 is 15 and 15 is less than 24 not greater than 24
A. IS FALSE
b is 3 (4) + 4 (3)>24 this is false because 3 times 4 equals 12 and 4 times three equals 12
12 plus 12 equals 24 and 24 is equaled to 24 not greater than
B IS FALSE
c is 3 (-2)+4(9)>24
3 times -2 is -6 plus 4 times 9 which is 36 is 30 30 is greater than 24 so
C IS TRUE
