Answer:
V=20
Step-by-step explanation:
Simplify both sides of the equation.
4−2(v+9)=26
4+(−2)(v)+(−2)(9)=26(Distribute)
4+−2v+−18=26
(−2v)+(4+−18)=26(Combine Like Terms)
−2v+−14=26
−2v−14=26
Step 2: Add 14 to both sides.
−2v−14+14=26+14
−2v=40
Step 3: Divide both sides by -2.
−2v
−2
=
40
−2
v=−20
The second one is a perfect square trinomial
X^2+16x+64
Distribute first.
.75 times 8 + .75 times e, which is 6+.75e = 2-1.25e
Then subtract 2 from both sides,
4+.75n=-1.25e
Next subtract .75 from both sides,
4=-2e
Divide both sides by -2, and you will get e= -2. Hope this helps!
Answer:
-5
Step-by-step explanation:
-9+x = -14
Add 9 to each side
-9+x+9 = -14+9
x = -5
X=7.
9x-7y=63
9x-7 x 0=63
9x - 0=63
9x=63
X=7.
Y=-9
9 x 0 -7y=63
