Answer:
d) 2x(4x + 2)
Step-by-step explanation:
a) 4(2x + 1) = 8x + 4
b) 1/2(16x + 8) = 8x + 4
c) 2(4x + 2) = 8x + 4
d) 2x(4x + 2) = 8x² + 4x
Answer:
1. Find < ACB
2. Use that triangles =180 to find <B = 41
Step-by-step explanation:
1.We need to find < ACB
<ACB +<DBC= 180 They make a straight line
Subtract DBC from each side
<ACB = 180 - <DBC
We know DCB = 113
ACB = 180 -113
ACB = 67
2.The three angles of a triangle = 180, so we can then find <B
<A +<B + <ACB = 180
72 + B + 67 = 180
Combine like terms
139+ <B = 180
Subtract 139 from each side
<B = 180-139
<B =41
Answer:
3x+1 1/2=10
Step-by-step explanation:
Took test, its correct
The two triangles are similar, so the corresponding sides have the same ratio:
5/8 = x/4
x = 20/8 = 2.5
x = 2.5
Acrually called a mixed number, for instance 3 and 5/8 multiply the denominator by the whole number and then add the numerator. 3x8 = 24 +5 =29/8.
