Answer: c. explanation: you would just use the distributive property then you would add like terms do get your answer. heres my work: -(z+1) + 2(z-2) —> -z-1 + 2z-4 —> z-5
Answer:
14.4 inches to the nearest tenth.
Step-by-step explanation:
The square has area x^2 where x is the length of each side so:
x^2 = 13
x = √13.
The perimeter is the distance all around the square and this is 4x so we have the answer 4 *√13
14.422 inches.
1. The remaing area of the yard will be found as follows:
Area of the yard
A1=length*width=10x*15x=150x^2 yd^2
area of the fountain
A2=πr²
A2=π(4x)²
=50.266x^2
The remaining area will be:
A=150x^2-50.266x^2
A=99.735x^2 yd^2
2] Area left for bleachers, restrooms and other parts of the stadium will be as follows:
Area of the lot is:
A1=length*width
A1=8x×12x= 96x^2
Area of the field
A2=length×width
A2=3x×6x=18x^2
Hence the remaining area will be:
A1-A2
=96x^2-18x^2
=78x^2 sq. units
Z-Score= x-value minus mean (average) / standard deviation so z score equals -2.16 or 1.54% below the mean based on table a
