×imagine this is a flattened pyramid box. When you fold along the dotted lines you can see which sides are equivalent.
Add up the areas of each piece.
Two identical rectangular pieces 7 × 10
2(7)(10) = 140
One small rectangular piece 6 × 7
7(6) = 42
Two identical triangles
2(0.5)(6)(8) = 48
Add up all the pieces
140 + 42 + 48 = 230
Answer:
The complement is 53 and the supplement is 143
Step-by-step explanation:
Two complementary angles add to 90
PQR and x = 90
37+x = 90
Subtract 37 from each side
37-37 +x =90-37
x = 53
The complement is 53
Two supplementary angles add to 180 degrees
PQR and x = 180
37+x = 180
Subtract 37 from each side
37-37 +x= 180-37
x = 143
The supplement is 143
Answer:
f(3) = - 18
Step-by-step explanation:
To evaluate f(3) , substitute x = 3 into f(x) , that is
f(3) = - 4(3 + 1) - 2 = - 4(4) - 2 = - 16 - 2 = - 18
Answer:
Step-by-step explanation:
48% of n = 0.48n = 40.32
n = 84
20% of n = 0.20*84 = 16.8
Answer:
-2
Step-by-step explanation:
Just use 6-8 and you will get - 2
Check again with - 2+8 you will get positive 6
