The formula for the area of a square is:
A = s²
Area = side²
We know that area (A) is 20 ft²
20 = s²
Now we must find the length of the side (s). To do this we must get rid of the square. To remove the square from s take the square root of both sides:
√20 = √s²
s ≈ 4.5 ft <<< approximate answer
To find the exact answer you must simplify the square root:
s = 2√5 ft <<< exact answer
Each side of the square is exactly 2√5 or approximately 4.5

As the x value increases by 1 the y value increases by 6. The x value skips from 4 to 25 whihc means it increased by 21.The y value 21 * 6 + 11 or 137 when x is 25

Answer:
B. 17°
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relations between angles and sides. Here, the relevant relation is ...
Sin = Opposite/Hypotenuse
sin(N) = PQ/PN
sin(N) = 4/14
N = arcsin(4/14) ≈ 16.6° . . . . use the inverse function to find the angle
N ≈ 17°
Answer:
x=30
Step-by-step explanation:
3(x+2)^3/5 +3=27
Subtract 3 from each side
3(x+2)^3/5 +3-3=27-3
3(x+2)^3/5 =24
Divide by 3
3/3(x+2)^3/5 =24/3
(x+2)^3/5 =8
Take everything to the 5/3 power to get rid of the exponent on the left side
(x+2)^3/5 ^ 5/3=8 ^ 5/3
Remember that a^b^c = a^ (b*c)
(x+2)^(3/5 * 5/3)=8 ^ 5/3
(x+2)=8 ^ 5/3
Replace 8 with 2^3
(x+2)=2^3 ^ 5/3
Remember that a^b^c = a^ (b*c)
(x+2)=2^(3 * 5/3)
x+2 = 2^5
x+2 = 32
Subtract 2 from each side
x+2-2 = 32-2
x=30
Answer:
Let height be h
Base be B
thereforeNew area=(base+1)(hieght+1)
=(b+1)(h+1)
=bh+h+b+1
