Answer: Make sure all words are spelled correctly.
Try different keywords.
Try more general keywords.
Try fewer keywords.
Step-by-step explanation:
2.5x + x = 455
3.5x = 455
455/3.5 = x
x = 130
corn : 325
lettuce: 130
The scale would be 10 units. The scale is always multiplied. So if the drawing is 7 units, multiplying by 10 will give you the actual length of 70.
Answer:
C and D
Step-by-step explanation:
The quadratic formula is
x= (-b±√b²-4ac)/2a
The formula uses the numerical coefficients in the quadratic equation.
The general quadratic equation is ax²+bx+c where a, b and c are the numerical coefficients
So, lets try and see;
A.
But due to the fact that in this equation you have x⁴, the equation is not a quadratic equation thus can not be solved using this formula
B
C
D.
From the checking above, the equations will be C and D
