Sandy is working with a carpenter to frame a house. They are using -foot-long boards, but each board must be cut to be feet, inches long. How much is cut off each board?.

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof

(5x-1)^2= (5x)^2-2(5x)×1+(1)^2=25x^2-10x+1

parallelogram is the   answer

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
