1.1 Factoring: 4x2+9y2+16z2-6xy-12yz-8xz
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: -6xy-12yz
Group 2: 16z2-8xz
Group 3: 4x2+9y2
Pull out from each group separately :
Group 1: (x+2z) • (-6y)
Group 2: (x-2z) • (-8z)
Group 3: (4x2+9y2) • (1)
Looking for common sub-expressions :
Group 1: (x+2z) • (-6y)
Group 3: (4x2+9y2) • (1)
Group 2: (x-2z) • (-8z)
Answer:
B.
Step-by-step explanation:
In statement (1), we are given that m∠BAC=m∠BCA
If the two angles are congruent, this means that the sides opposite the angles are also congruent. These sides are AB and BC. Therefore:
AB=BC | B. sides opposite equal angles are equal
:Done
*The side opposite a given angle is the side towards which the angle opens up to. For example, ∠BAC opens up towards the side BC, and ∠BCA opens up towards side BA.
Answer:
20
Step-by-step explanation:
30+30 is a hour and half of 30 is 15 so do this 8+8 and the add half of 8 and it is 4 so the full thing is 8+8+4+20
