Answer:
x = -3/2 x =0
Step-by-step explanation:
(2x+3) ^2 - 6x-9 = 0
Factor out -3 from the last 2 terms
(2x+3) ^2 - 3( 2x+3) = 0
Let m = 2x+3
m^2 - 3m = 0
Factor out m
m(m-3) =0
Using the zero product property
m=0 m-3 =0
m=0 m=3
Substitute 2x+3 back in for m since we are looking for the value of x
2x+3 =0 2x+3 =3
2x +3-3=0-3 2x+3-3=3-3
2x = -3 2x=0
0
x and x are same terms.
TNX for da points
ahhhhhhhhhhhhhhhhhh
X=-1
Y=-9
x^2+2x-8
x^2+2x +1 =8+1
(x+1)-9
160 in²
The formula for the area of a triangle is ...
A = 1/2bh . . . . base length b, height h
Here, the triangle has a base length of 32 in, and a height of 10 in. Its area is ...
A = 1/2(32 in)(10 in) = 160 in²
Large=40 pounds
small=30 pounds
and this is the solution
