Here's the solution,
the volume of the given figure is :
=》
volume of pyramid :
=》
=》
=》
=》
volume of pyramid = 40 cm³
now, volume of rectangular prism :
=》
=》
=》
volume of rectangular prism = 40 cm³
volume of composite figure = 40 + 40
=》80 cm³

Step-by-step explanation:
no
the answers as follows
a) 16 b) 13 c) 16 d) 46 e) -630 f) 18 g) -32 h) 50 i) -6 j)38 l)61
Step-by-step explanation:
a) p + 9 = 7 + 9 = 16
b) p - s = 7 - (-4) = 7 + 4 = 13
c) r - q = 10 - (-6) = 16
d)q + 52 = -6 + 52 = 46
e) pqr = 7 X (-6) X 10 = -630
f) r + 8 = 10 + 8 = 18
g) pq + r = 7 X (-6) + 10 = -42 + 10 = -32
h) r - qs = 10 - (10 X (-4))= 10 + 40 = 50
i) 3r + 6q = 3 X 10 + 6 X (-6) = 30 - 36 = -6
j) 59 - 3p = 59 - 3 X 7 = 59 - 21 = 38
k) check your question
l) 4q + 85 = 4 x (-6) + 85 = -24 + 85 = 61
Answer: 2((x+y)-21)
Calculation/Explanation:
Twice the sum of x and y decreased by 21 means that you must add x and y first before decreasing by 21. The last step is to double the whole equation that we just performed.
