math is a subject that was made to ... umm... torture kids & make them mentally depressed!! kidding...so NOT!
Answer:
142125
Step-by-step explanation:
Since we given two brackets to solve we will have to take the step by step procedure
So let's solve the question
(2+377)(2-377)
Let's start with the first bracket
(2+377)
It will give us 379
So let's solve the second bracket
(2-377)
It will give us -375
So back to the question
(379)(-375)
142125
So the final answer is 142125
Answer:
speed=d/t
let him cover x distance while walking
running d=4.5-x
s1=x/0.5 km/hr....(1)
s2=4.5-x//5/12.....(2)
atq.....s2=2+s1
s1=2x
s2=54-12x/5
by eqn 1 and 2
s1+s2=2x+54-12x/5
putting value of s2
s1+2+s1=2x+54-12x/5....taking LCM =5
10s1+10= 10x+54-12x
as s1=2x
10s1+10= -2x+54
10s1+10=-s1+54
11s1=44
speed when walking=4km/hr
Answer:
136=x
Step-by-step explanation:
When an angle is shown, the one opposite of it is equal to the forst equation. The bottom angles are equal to 360ñ so if you take 46x2=92. Subtract 92 by 360 to get 268. Divide it by 2 to get one of the bigger angles, which is 134 degrees. And as for the top, one angle on the bottom is equal to the same spot on the top. so, 136=x
