Answer:
231 feet below the surface, -231
Step-by-step explanation:
7 minutes, 33 fpm
descending,
-33 * 7,
to solve without calculator;
(-30 + (-3)) * 7
-30 * 7 + (-3) * 7
-210 + (-21)
= -231
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((3x2 + 2x) - 1) - (x2 - 3x + 4)
Step 2 :
Trying to factor by splitting the middle term
2.1 Factoring 2x2+5x-5
The first term is, 2x2 its coefficient is 2 .
The middle term is, +5x its coefficient is 5 .
The last term, "the constant", is -5
Step-1 : Multiply the coefficient of the first term by the constant 2 • -5 = -10
Step-2 : Find two factors of -10 whose sum equals the coefficient of the middle term, which is 5 .
-10 + 1 = -9
-5 + 2 = -3
-2 + 5 = 3
-1 + 10 = 9
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
Final result :
2x2 + 5x - 5
brainliest plz tried rlly hard on this
Answer:
28h = 56
Divide by 28 on both sides
H = 2
The correct is 44 because you estamate and 48 is close to 44
