A bookmark has an area of 21 square centimeters. Its perimeter is 20 centimeters. What are the dimensions of the bookmark?
Answers
Answer: The dimensions are 7cm and 3cm.
Step-by-step explanation:
The following equation can be deduced from the question
L × W = 21 ....... i
2L + 2W = 20 .......... ii
Divide equation ii through by 2
(2L + 2W = 20) / 2
L + W = 10 ....... iii
From equation iii
L = 10 - W ......... iv
Put equation iv into I
L × W = 21
(10 - W) × W = 21
10W - W² = 21
W² - 10W + 21 = 0
W² - 7W - 3W + 21 = 0
W(W - 7) - 3(W - 7) = 0
W - 3 = 0
W = 0+3
W = 3 centimeter
Since,
Length × Width = 21
Length = 21/3
Length = 7 centimeters
The dimensions are 7cm and 3cm.

{b,c,d,f,g,h}

since P and Q share the same letter you're putting “A” in the middle where the two intersect. since U have B and Q have b we're putting it outside. so Q only supposed to have G. P is empty and U now have B,C,D,F,H.
p^1- p complement means everything outside of P so that will be b,c,d,f,g,h.

Solve for y convert the equation 10x+2y=12 from standard form to slope intercept form
Answers
10x=12-2y
10x-12=-2y
-5x+6=y
x = 2y − 4
7x + 5y = −66
Answers
Answer:
Step-by-step explanation
Substitute 2y-1 for x in the second equation:
7x + 5y = -66
7(2y-4) + 5y = -66
then solve for y:
14y - 28 + 5y = -66
19y = -38
y = -2
Substitute -2 for y in the first equation:
x = 2y - 4
x = 2(-2) - 4
x = -8
The lines intersect at (-8,-2)
