Answer:
I think question is:
(x+4x+2)(2x^2+3x-4)
:(5x+2)(2x^2+3x-4)
5x(2x^2+3x-4)+2(2x^2+3x-4)
10x^3+15x^2-20x+4x^2+6x-8
10x^3+19x^2-14x-8
Answer:
Part 1) The speed is
Part 2)
Step-by-step explanation:
Part 1
<em>What is this speed on feet per second?</em>
we know that
1 hour=60 min
1 min=60 sec
so
1 hour=60*60=3.600 sec
1 mi=5,280 ft
we have
Convert mi/h to ft/sec
Part 2
At this speed how many feet will the parachutists fall during 10 seconds on free fall?
Multiply the speed by the time to obtain the distance
so
Answer:
1. congruent
corresponding
2.supplementary
same side interior

Answer:
12
Step-by-step explanation:
12 × 2 = 24 and 6 + 6 + 6 + 6 = 24
Step-by-step explanation:
1a)you are asked to find the number of girls and boys who received prizes
1b)The given facts are that out of 60 pupils, 40 being boys, 20 being girls, joined a Math Quiz competition. 20%of boys and 15 of girls received prizes.
1c)40 boys +20 girls=60 pupils.
1d) Find the number of girls and boys that re ceived prizes
20% of 40 boys
20/100 ×40= 8 boys won prizes
15% of 20 girls
15/100×20=3 girls won prizes
1d) 8 boys+3 girls=11 pupils won prizes
