Answer:
7/5
Step-by-step explanation:
1 2/5, a mixed number, is equivalent to 7/5.
3x^2 + 21x
Is the answer without a doubt.
The length of each side of the larger square is 8 cm.
<u>Step-by-step explanation</u>:
Step 1 ;
- The combined area of two squares = 80 sq.cm
- The side of small square = x
- The side of larger square = 2x
Step 2 :
Area of the square = a^2
Area of small square + area of large square = 80
x^2 + (2x)^2 = 80
x^2 + 4x^2 = 80
5x^2 = 80
x^2 = 80/5
x^2 = 16
x = ±4
Step 3 :
Since length cannot be negative, the value of x= 4
∴ The length of the side of small square = 4cm
The length of the side of larger square = 2x = 8cm
Tangent is opposite/adjacent so it would 60/25 which simplifies to 12/5
F(x)=-4(-1)-5
f(x)=4-5
f(x)= -1
-1 is your answer
