The appropriate choice is
Polynomial B. -3x⁴ +5x³ +5
_____
C and D are not trinomials. (They have 4 terms, not 3.) A is 5th degree, not 4th.
13-k
Explanation: it’s just 13 minus the number k
Answer:
924 cm²
Step-by-step explanation:
The surface area is equal to the area of the two triangles + area of the three rectangles.
Area of two triangles:
12 × (9+5) × 1/2
= 84
84(2) = 168
Area of the three rectangles:
15 × 20 + 13 × 20 + 14 × 20
= 840
840 + 84
The surface area of the triangular prism is 924 cm².
Answer:
A: $8xN= $25 (N=5 days)
B: $8xN= $56 (N= 7 days)
Step-by-step explanation:
Hope This Helps! ;)
no real solutions
The conditions for the discriminant are
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then no real solutions
