Answer:
x=-7 x=4
Step-by-step explanation:
(X-2)(x+5)=18
FOIL
x^2 +5x -2x-10 =18
Combine like terms
x^2 +3x -10 = 18
Subtract 18 from each side
x^2 +3x -10 -18 = 0
Combine like terms
x^2 +3x -28 =0
Factor
What two numbers multiply to -28 and add to 3
7*-4 = -28
7+-4 = 3
( x+7) ( x-4) =0
Using the zero product property
x+7 =0 x-4=0
x=-7 x=4
The <em><u>correct answer</u></em> is:
HL
Explanation:
These will both be right triangles, as angle Q and angle Q' are both 90 degrees.
Since Q and Q' are the right angles, this means that RS and R'S' are the hypotenuses of the two right triangles.
Since Q'R'S' was created by translating QRS, a corresponding leg of both triangles will be congruent; this gives us hypotenuse-leg, or HL.

Answer:-4×8=-36 -4+8=4
Step-by-step explanation:
you cant get 5 its impossible unless you do some crazy wizardry stuff but you do -4×8 witch equals -36 then you do -4+8 witch equals 4 hope I did this correctly >^<
