4(b - 6) + 19 # Starting equation
4b - 24 + 19 # Using the distributive property
4b - 5 # Simplified expression
Answer:
JK = 24
Step-by-step explanation:
Δ BKJ and Δ BCA are similar triangles and ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
5JK = 120 ( divide both sides by 5 )
JK = 24
10+10=20, 15+5=20 Those are both addition sentences that have a sum of 20.
