The longest side must be less than the sum of the other 2 sides.
5, 12 and 13 - can be constructed
2, 11 and 15 - can be constructed
3, 7 and 11 - CAN'T be constructed - the longest side is greater than the sum of the other two.

Answer: x = -4 or x = 7

Step-by-step explanation:

x^2 - 3x - 28 =/>

(factor)

(x^2 + 4)(x-7) = 0

x + 4 = 0 or x - 7 = 0

(subtract -4 from 0 and 7 from 0)

x = -4 or x =7

A box of 25 light bulbs is shipped to a hardware store.when it arrives,four of the bulbs are broken.predict the number of broken

anyanavicka [17]

First you need to divide 125 / 25 which is 5 then you do subtraction 21 x 5 which is 105, then you subtract again 125 - 105 which is 20, 20 light bulbs will be broken. Or you could have just multiplied 5 by 4 which is the amount of light bulbs that were broken which is a lot easier...

The set of numbers 1, 7, 11 and 36 contains values for m. What value of m makes the equation below true?

Arada [10]

Answer:

Step-by-step explanation:

If m was 1, then it would be

4 +8 = 36, which is not true.

If m was 7, then it would be

28 + 8 = 36, which is true.

If m was 11, then it would be

44 + 8 = 36, which is not true.

If m was 36, then it would be

144 + 8 = 36, which is not true.

Hope that helps!

Lelu [443]

Answer:

Jaden has to plant the geranium in the circumcentre of the triangular yard in order such that it is equidistant from all its vertices.

Step-by-step explanation:

In Jaden’s yard, there is a triangular garden patch. He wants to plant a geranium in the patch at a point equidistant from all its vertices.

" The CIRCUMCENTER (C) of a triangle is the point in the plane equidistant from the three vertices of the triangle "

Hence Jaden has to plant the geranium in the circumcentre of the triangular yard in order such that it is equidistant from all its vertices.
