L = 10a + a
L = 11 a
W = 1/10 (11a)
W = 1.1 a
Perimeter = 2(L + W)
Perimeter = 2*(11a + 1.1a)
Perimeter = 22a + 2.2 a
Perimeter = 24.2 a
Area = L * W
Area = 11a * 1.1a
Area = 12.1 a^2
The perimeter is 2*area
P = 2*A
P = 2* 12.1 a^2
P = 24.2 a^2
Now put in the perimeter on the left side of the above equation.
24.2a = 24.2 a^2 Divide both sides by 24.2
1 a = a^2 Divide by a
1 = a
The length = 11*a = 11*1 = 11
The Width = 1.1 a = 1.1 * 1 = 1.1

Answer:
11 books
Step-by-step explanation:
because if she gets $4 per book and gets $44 in total then that means she has read 11 books because 4 times 11 is 44.
Put the x where the y is and the y where the x is
X=-3(y+4)
Solve for y
X=-3y-12
Add 12 to both sides
X+12=-3y
Divide both sides by -3
X/-3+ 12=y
Answer:
C
Step-by-step explanation:
4x-10+2x+15+x=180
7x+5=180
7x=175
x=25
So 2x+15=65 and 4x-10=90.
90+65+25=180
So your triangle is a right triangle.
Answer:
B
Step-by-step explanation:
Comparing like terms on both sides
→ x²
Note that x² = ![\sqrt[3]{x^{6} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7Bx%5E%7B6%7D%20%7D)
→ 
Note that = ![\sqrt[3]{y^{12} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7By%5E%7B12%7D%20%7D)
Also
54 → 3
Note that 54 = 3³ × 2
and ![\sqrt[3]{54}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B54%7D)
= ![\sqrt[3]{3^{3}(2) }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B3%5E%7B3%7D%282%29%20%7D)
= 3![\sqrt[3]{2}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B2%7D)
Hence
![\sqrt[3]{54x^{6}y^{12} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B54x%5E%7B6%7Dy%5E%7B12%7D%20%20%7D)
= 3x²
Hence n = 3 → B
