Answer:u= -30
Step-by-step explanation:
Answer:
4.6 km
Step-by-step explanation:
-This is a Pythagorean Theorem problem where the distances walked are effectively the base and height of the imaginary right triangle thereof.
#Apply Pythagorean theorem to solve:


Hence, the distance x is 4.6 km
10*7*5=350 in3, the volume of 1 brick
14,000 in3 is the volume of all the concrete
Let X=the number of bricks
350*X=14000
X=14000/350
X=40 bricks
Answer:
x<-5 . All you have to do is pemdas which is parentheses,exponents, multiplication, division, addition and subtraction
(x-6)(x+6)
solve just to make sure
x^2+6x-6x-36
combine like terms
x^2-36
