Which is the solution t other equation (x-2)(x+5)=18

(x-2)(x+5)=18

x²-2x+5x-10 =18

x² + 3x -28 = 0 -28 = 7*(-4), 3=7+(-4)

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

x= - 7, x=4

(x-2)(x+5)=18

\\expand expression

x² -2x + 5x - 10 = 18

\\combine like terms

x² + 3x - 10 = 18

\\Take away 18 from both sides

x² + 3x - 28 = 0

\\factorise x² + 3x - 28

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

\\apply zero product property

x + 7 = 0 or x - 4 = 0

\\Evaluate

x = -7 or x = 4

x = -7 or 4

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
