Step-by-step explanation:
area of triangular endface = ½×6×8 = 24 cm²
area of rectangular endface = 4×8 = 32 cm²
area of each endface = 24+32 = 56 cm²
area of each 3×10 face = 30 cm²
area of 3×4 face = 12 cm²
area of base = 8×3 = 24 cm²
surface area = 2×56 + 2×30 + 12 + 24 = 208 cm²
Answer:
- 5
Step-by-step explanation:
Note that
(x + y)² = x² + 2xy + y², thus
x² + y² = (x + y)² - 2xy ← substitute given values
= 5² - 2(15)
= 25 - 30
= - 5
The answer is 4x^2- 19x -30
