I is equal to negative 1
1) 5-2i or 5-2
2) 7-3i or 7-3
sqrt (b^2 -4ac ) =sqrt (4-4•3•4) = sqrt (-44) so the parabola does not have real solutions. Answer C)
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
Answer:
4p - 6t
Step-by-step explanation:
7p + 9t - 3p - 15t
= 7p - 3p + 9t - 15t
= 4p + (-6t)
= 4p - 6t
A GCF(or greates common factor) is exactly that the greates number taht can be used to divide both numbers. In this case 32 and -48 is 8 how do I know that because 8 times 4 is 32 and 8 times 6 is 48, now that you know that, I will leave unly the numbers that I used to multiply by 8 this would be 4 and 6, now that doesn't mean 8 is your GCF you have to check if your numbers can be simplified even more with another number well in this case yes 4 and 6 also share a common number ans this one is 2 4 divide by 2 is 2 and 6 divide by 2 is 3 now we are left with these numbers 2 and -3, now how do I know what was my GCF well this part is easy, just multiply the first number you used to divide times the second
E.J. in this case you would multiply 8 times 2 and this gives you 16... Now how do you know if this GCF is correct well multiply 16 times (2-3) usinf distributive property, 16 times 2 is 32 so we are good till now, and 16 times 3 is in fact -48 s our GCF is correct!!! this means 16(2-3) is our final answer
Hope this helps
