Answer:

GL=10

x=7

this is formula when the KL in mipoint of both lines

that means HJ=LJ

and HK=KG

when you see this that means

2KL=GJ

150-20x=x+3

147=21x

x=7

and he want GL measure

so 7+3=10

hopefully its helpful and correct

have a great day

Answer:

KL=1/2*GJ

75-10x=1/2*x+3

2(75-10x)=x+3

150-20x=x+3

150-3=x+20x

147=21x

147/21=x

7=x

substitute the value of GJ

x+3

7+3

10

Step-by-step explanation:

Note :KL=1/2*GK because the the straight line joining the mid points of two sides of a triangle is parallel to the third side and equal to half of it.

Which value must be added to the expression x2 + 12x to make it a perfect-square trinomial?
denis23 [38]

36 is must be added to the expression x² + 12x to make it

perfect-square trinomial

Step-by-step explanation:

The perfect-square trinomial x² + 2ax + a² = (x + a)², then

1. The first term in the trinomial is square the 1st term in the bracket

2. The middle term in the trinomial is the product of 1st , 2nd

    terms of the bracket and 2

3. The 3rd term in the trinomial is square the 2nd term in the bracket

∵ The expression is x² + 12x

∵ We must add the 3rd term which make it perfect-square trinomial

- Divide 12x by 2 to find the product of the 1st term and 2nd term

  in the bracket

∵ 12x ÷ 2 = 6x

∴ The 1st term is x and the 2nd term is 6 of the bracket

∵ The 3rd term in the trinomial is square the 2nd term in the bracket

∴ The 3rd term in the trinomial is 6² = 36

∴ x² + 12x + 36 = (x + 6)²

36 is must be added to the expression x² + 12x to make it

perfect-square trinomial
