Digging -28 would take 16 hours because 14 times 2 equals 28 and 8 times 2 equals 16 so answer is 16
Answer:
Acute angle
Step-by-step explanation:
Given that m<C =
, to find out the type of angle angle C is, evaluate the expression given by substituting x = 13, in the expression.
m<C = 
m<C = 
m<C = 
m<C = 76°
Acute angles are less than 90°.
m<C is less than 90°, therefore it is an acute angle.
Answer:
x-2
Step-by-step explanation:
x3−3x2+3x−2/x2−x+1
=
x3−3x2+3x−2/x2−x+1
=
(x−2)(x2−x+1)/x2−x+1
=x−2
Answer:
Step-by-step explanation:
4x - 5(x + 3) Remove the brackets. Watch the - sign and -5*3
4x - 5x - 15 Combine the xs
-x - 15
Answer:

Step-by-step explanation:
Given expression:
2x + 5y = -10
The equation of a straight line is;
y = mx + c
y and x are the coordinates
m is the slope
c is the intercept
Now;
let us write the given expression in slope intercept format;
2x + 5y = -10
5y = -2x - 10
y =
- 2
So, the slope of the line is
