There is no formula for finding prime numbers. The rule is just if a number is prime then it is divisible by 1 and itself
Answer:
z+9(8−x)+8(z+8)=
z+72-9x+8z+64=
9z-9x+136
<u> </u>
(3−10)^2−(5−12)^2 parenthesis first
(-7)²-(-7)²=
49-(49)=49-49=0
<u> </u>
2^2⋅4^3 exponent first
2*2*4*4*4
4*64=256

Step-by-step explanation:
Answer:
627square inches
Step-by-step explanation:
Area of the composite figure.. = area of triangle + area of parallelogram
Since the triangle is an equilateral triangle;
Area of the triangle = r²sintheta
Area of the triangle = 18²sin60
Area of the triangle = 324sin60
Area of the triangle = 324(0.8860)
Area of the triangle = 280.584 square in
Area of the triangle = 281 square inches
Area of parallelogram = absintheta
Area of parallelogram = 20(20)sin60
Area of parallelogram = 400(0.8660)
Area of parallelogram = 346.4square inches
Area of parallelogram = 346 square inches
Area of the figure = 346 + 281
Area of the figure = 627square inches
