Answer:
7x2 + 14x = 0
x2 + 3x -5 = 0
x2 - x = 3x + 7
Step-by-step explanation:
A quadratic equation has the highest power of x to the second power. It must have x to the second power
7x2 + 14x = 0 quadratic
x3 - 3x2 + 1 = 0 not quadratic but cubic
5x - 7 = 0 not quadratic but linear
x2 + 3x -5 = 0 quadratic
x - 5 = 9x + 7 not quadratic but linear
x2 - x = 3x + 7 quadratic
The answer would be B) 80
To find the answer you would use the equation x/250 = 32/100. Then, you would cross multiply (multiply diagonally). This would leave you with 100x=8000. Finally you divide by 100 on n=both sides of the equal sign, leaving you with x=80.
Answer:
a) 60
b) 33
c)70
d)65
Step-by-step explanation:
Use BIDMAS
(brackets, indicies, division, multiplication, addition, subtraction)
Answer:
C
Step-by-step explanation:
Both C and D have the correct ratio. (5/15=1/3)
But I’m thinking the answer is C because it’s orientation is landscape, not portrait, which would be important in artwork.
