There are 12 inches in a foot. If he needs 4 feet, and 4 times 12 equals 48, then he needs 4 more inches.

Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Sarah, Jose and you live in the same street:
Distance between you and Jose = 5 blocks
Distance between Jose and Sarah = 2 blocks
Distance (b) between you and Sarah:
Since it isn't stated whether Sarah lives closer to you than Jose or vice versa ;
Then;
Distance b between you and Sarah will be :
(Distance between you and Jose ± distance between Jose and Sarah)
b = (5 ± 2)
b = (5 + 2) or (5 - 2)
b = 7 blocks or 3 blocks
Answer:
x = 100°
Step-by-step explanation:
in the given figure
(x + 23°) + 57° = 180°
(they form linear pair)
- x + 23° + 57° = 180°
- x + 80° = 180°
- x = 180° - 80°
- x = 100°
Among the coefficient signs (++-) there is one sign change, so Descarte's rule of signs tells you there is one positive real root. Changing x to -x does not affect the signs, so there is also one negative real root. Then there are two complex roots to bring the total number to 4, the degree of the polynomial.
The factorization is
f(x) = (x^2 +25)(x^2 -4)
Each of these can be factored using the form for factoring the difference of squares.
f(x) = (x -5i)(x +5i)(x -2)(x +2)
There are 2 real roots: ±2.
There are 2 imaginary roots: ±5i.
