Answer:
W= 50
Step-by-step explanation:
log(w)+log(2)=2
log(w)+0.30103=2
Step 1: Add -0.30103 to both sides.
log(w)+0.30103+−0.30103=2+−0.30103
log(w)+0=1.69897
Step 2: Divide both sides by 1.
log(w)+01=1.698971
log(w)=1.69897
Step 3: Solve Logarithm.
10log(w)=101.69897(Take exponent of both sides)
w=101.69897
w=50
Hope this helped
c is the anser
x = 1/2, y = 17/2
x = -3, y = 12
x²-9=x²-3²=(x+3)(x-3)
use formula
a²-b²=(a+b)(a-b)
