Answer:
- 0 real zeros
- 2 complex zeros
Step-by-step explanation:
The "fundamental theorem of algebra" says a polynomial of degree n will have n zeros. If the polynomial has real coefficients, the complex zeros will appear in conjugate pairs.
The graph of this quadratic (degree = 2) does not cross the x-axis, so there are no real values of x that make y=0. That means the two zeros are both complex.
Answer:
x=4
Step-by-step explanation:
5(2x - 1) = 35
Should expand so....
10x - 5 = 35
10x = 40
x = 4
Remember that one foot is 12 inches.
So a 57 inch person would be 4 feet, 9 inches.
Good luck!
Answer:
4cm
Step-by-step explanation:
To find the answer, if its a cube, that means all of is sides are equal.
Since to find volume, we use the equation width*height*length, then we need to find the cube root of 64.
Since 8*8 is the square root of 64, lets divide it in half.
8/2=4
4*4=16*4=64.
The cube root of 64 is 4 so the length of the sides is 4.
Hope this helps!
