Answer:

(-\infty,-4]

Step-by-step explanation:

So we have the inequality:

x\leq -4

This means that our solution is all numbers <em>less than or equal to </em>-4. Therefore, in interval notation, this is:

(-\infty,-4]

This represents all the numbers from negative infinity up until -4. This is equivalent to the inequality.

The base of an isosceles triangle is 43m The perimeter of the triangle is 4215 cm what is the lenght of either of the remaining
zaharov [31]

Let the length of equal sides be x cm. Perimeter = x cm + x cm + Base = 4 2/15 cm 2x + 4/3 = 62/15 On transposing 4/3 to R.H.S, we obtain 2x = 62/15 - 4/3 2x = 62 - 4 x 5/15 = 62 - 20/15 2x = 42/15 On dividing both sides by 2, we obtain 2x/2 = 42/15 x1/2 x = 7/5 = 1 2/5 Therefore, the length of equal sides is 1 2/5 c m.
