17) Part A: A store orders flour that comes in 10 pound bags and 20 pound 5 points bags. The number of 20 pound bags is 20 more than twice the number of
10 pound bags. Which expression represents the number of 20 pound
bags?
A : 2x+20
B : x+2
C : x+20
D : 2 (x+20)

Factorize: x^2+8x+10 i just solved it but i don't know if the process is correct

What is the effect on the graph of the function f(x)=x when f(x) is replaced with -f(x)+4

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
