Answer:
x=-11/8
Step-by-step explanation:
First use the Distributive property on [3(2x-1)]:
5x+6x-3=3x-14
Now combine alike terms:
11x-3=3x-14
Now add three to both sides:
11x=3x-11
Now subtract 3x from both sides:
8x=-11
Now divide both sides by 8:
x=-11/8
This fraction cannot be simplified meaning your final answer SHOULD be -11/8
Each side of the smaller square is the hypotenuse of the triangles with legs of 3 and 4. From the Pythagorean Theorem, we can calculate the hypotenuse:
hypotenuse^2 = 3^2 + 4^2
hypotenuse^2 = 9 + 16
hypotenuse^2 = 25
hypotenuse = 5
Therefore, the area of the smaller square is 5 * 5 = 25
Step-by-step explanation:
a) r=d/t ( same as formula of speed)
b) r= 665280/3=221760 feet/hr
c) distance in miles = 665280/5280= 126
so r=126/3 = 42 miles/hr
d) i think using miles makes more sense cz using feet will result in greater number of values so there is a greater chance of human error
Answer:
it is c
