Answer:
10/9
Step-by-step explanation:
What you need to do is change the division sign into a multiplication sign and flip the last quotient to 8/3.
5/12*8/3=10/9.
(2k, k) and (3k, 4k)
Slope = (4k - k )/(3k - 2k)
= 3k / k
= 3
Answer :
3
Answer:
0.625
Step-by-step explanation:
Fractions are another way to show two numbers being divided. The top number of the fraction (numerator) is divided by the bottom number (denominator).
In this case, it would be 5 divided by 8.
This equals 0.625, making 0.625 your answer.
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

Answers:
Perimeter = 88 inches
Area = 480 square inches
Answer:
MOP = DAB
Step-by-step explanation:
the sides have to be matched up as well. the side with only one dash (MO) has to correspond with the side with one dash from the other triangle (DA). Thus, the letters in the sequence (MOP) have to match up in the same order (DAB)
