Answer:
The answer is 1,550
Step-by-step explanation:
First you find the area of the rectangle 1
Area = ab
=(21 in) (17in)
=357 sq in.
this will be the same for rectangle 3 = 357 sq. in.
next find the area of rectangle 2
area=ac
=(21 in) (11 in)
=231 sq in.
this will be the same for rectangle 4 = 231 sq. in.
next find the area of rectangle 5
area = bc
=(17 in) (11 in.)
=187 sq. in
this will be the same for rectangle 6 = 187 sq. in.
Next add all areas together
Total surface area = 2(ac) + 2(ab) + 2(bc)
= 2(231) sq in. + 2(357) sq in. + 2(187) sq. in
= 462 + 174+ 374
= 1550 sq. in
Answer: True, True, True
Step-by-step explanation:
A. True. Angles B and C are congruent, and since B' is congruent to B, by the transitive property, C is congruent to B', and thus has the same measure.
B. True. AB>BC, and the rigid motions won't change the side lengths.
C. True for the same reason in B.
Answer:
Step-by-step explanation:
The xxx-coordinate of BBB is 333 less than the xxx-coordinate of AAA, or 8 - 38−38, minus, 3.
The yyy-coordinate of BBB is 111 greater than the yyy-coordinate of AAA, or -8 + 1−8+1minus, 8, plus, 1.
The coordinates of BBB are (5, -7)(5,−7)left parenthesis, 5, comma, minus, 7, right parenthesis.

pls refer to this answer and pls mark me brainliest as i have been waiting to be brainliest for almost 5 years pls
[8x-2y]+[3x-4y]
=8x+3x-2y-4y
=11x-6y
