Answer:
Both of these examples are wrong. You cannot add/subtract integers and square roots together, however, you could add square roots together if they have the same number under the square root. For example, 2 - 2√6 will stay as 2 - 2√6 because they aren't like terms. 25 + 5√5 + 5√5 + 5 = 30 + 10√5 because 25 + 5 = 30 and 5√5 + 5√5 = 10√5. We can add 5√5 and 5√5 together because they have the same number under the square root. If we were to compute √2 + √3, we would just leave it as is because they don't have the same number under the square root.
Step-by-step explanation:
the equations are :-
=》d = 40m + 200
=》d = 50m
here, by equalising both equations.
( since, d = d )
=》40m + 200 = 50m
=》50m - 40m = 200
=》10m = 200
=》m = 200 ÷ 10
=》m = 20
now,
=》d = 50m
=》d = 50 × 20
=》d = 1000
Good evening
Answer:
A) 6
Step-by-step explanation:
Firstly, the solution set to the inequality is : x > 7
Because, x + 8 > 15 ⇌ x > 15 - 8 ⇌ x > 7
Hence
The only number that is NOT in the solution set is 6
