Part (a)
The picture alone, without the frame, is 16 by 20
When accounting for the frame, the larger rectangle is 16+2x by 20+2x
We add up all four sides to get the perimeter
(16+2x)+(20+2x)+(16+2x)+(20+2x)
8x+72
or you can use this perimeter of a rectangle formula
P = 2(L+W)
P = 2(20+2x+16+2x)
P = 2(4x+36)
P = 8x+72
Answer: 8x+72
=========================================
Part (b)
Multiply the length and width to find the area of the rectangle.
area = length*width
A = L*W
A = (20+2x)*(16+2x)
A = 20(16+2x) + 2x(16+2x)
A = 320+40x + 32x + 4x^2
A = 4x^2 + 72x + 320
Answer: 4x^2 + 72x + 320
=========================================
Part (c)
Plug x = 2 into the perimeter equation found in part (a)
P = 8x+72
P = 8*2+72
P = 16+72
P = 88
Now plug x = 2 into the area equation found in part (b)
A = 4x^2 + 72x + 320
A = 4(2)^2 + 72(2) + 320
A = 4(4) + 72(2) + 320
A = 16 + 144 + 320
A = 160+320
A = 480

the number of small cars rented is 6.
The number of large cars rented is 8.
Step-by-step explanation:
Step 1 :
Each small car can hold = 5 people
Each large car can hold = 8 people
Step 2 :
Number of small cars rented = x
Number of large cars rented = x + 2
Step 3 :
Altogether the total cars can hold 94 people.
Total people = 5 people (No. of small cars) + 8 people (No. of large cars)
94 = 5 (x) + 8 (x+2)
94 = 5x + 8x + 16
78 = 13x
x = 78/13 = 6
∴ Number of small cars, x = 6 small cars
Number of large cars, x+2 = 8 large cars.
Answer: y = -3x - 6
Step-by-step explanation:
One way to write a <u>linear equation</u> is with slope-intercept form. Slope-intercept form is y = mx + b, where m is the slope, and b is the y-intercept.
Thus, the equation is y = -3x - 6
