Answer:
x=−6
Step-by-step explanation:
4x−5=x−23
Step 1: Subtract x from both sides.
4x−5−x=x−23−x
3x−5=−23
Step 2: Add 5 to both sides.
3x−5+5=−23+5
3x=−18
Step 3: Divide both sides by 3.
3x
/3=-18/3
x=-6
Answer:
See below
Step-by-step explanation:
sqrt(x^2+81)=x+10
x^2+81=x^2+20x+100 (which is one of the options)
81=20x+100
-19=20x
x=-19/20
So there's the work done.
44.5 and 135.5. The difference is 91

Step-by-step explanation: the 5 is in the hundred thousandths place.
Answer:
Step-by-step explanation:
a. HM = 14
HN = 21
HK = 10.5
Based on intersecting chords theorem,
HK*HJ = HM*HN
10.5*HJ = 14*21 (Substitution)
HJ = 294/10.5
HJ = 28
b. VC = 7.2
VG = 12
Based on tangent-secant theorem, thus:
VD*VC = VG²
VD*7.2 = 12²
VD = 144/7.2
VD = 20
Therefore,
CD = VD - VC
CD = 20 - 7.2
CD = 12.8
