Question 3. You divide 5 1/4 by 3/4 then multiply that by 20.
The answer is 140
Answer:
Option C is correct i.e. 2.
Step-by-step explanation:
Given the function is f(x) = x² +8x -2.
We can compare it with general quadratic expression i.e. ax² +bx +c.
Then a = 1, b = 8, c = -2.
We can find the number of real root by finding discriminant of the equation ax² +bx +c =0 as follows:-
D = b² -4ac
D = 8² -4*1*-2
D = 64 +8
D = 72.
When D is a positive value, then we have two real roots of the equation.
Hence, option C is correct i.e. 2.
Answer: -4
Step-by-step explanation:
Solve 2x+7=-1
2x. =-8
x. =-4
48 just count the inside of the triangle which is difficult since all side aren’t a full square or count the outside border of the triangle and just multiply I did 6x8
Answer:
Step-by-step explanation:
Find, find the total increase in salary for 7 years;
If 1 year = $4,000
7 years = ?
=7*4000
=28,000 in total
Original salary = $169,300
Add the total increase in salary to the original salary;
169,300 + 28,000 = 197,300
Therefore, in 7 years, the salary would be $197,300
