We want to factorize 6x² + 7x - 10
Note that
6x² = x * 6x or 3x * 2x
10 = 2 * 5 or 1 * 10
We can obtain 7x as (6x)*(2) - (x)*(5) = 12x - 5x = 7x.
Therefore
6x² + 7x - 10 = (6x - 5)(x + 2)
Answer: (6x - 5)(x + 2)
Answer: D
Step-by-step explanation:
multiply the denominators then the numerators
Answer:
The speed increases (45—>47—>49) then decreases (48—>47) over time.
Step-by-step explanation:
Do 72_16 u should probably get the answer
Answer:
Exercise 1:
base [b]=8cm
perpendicular [p]=6cm
hypotenuse [h]=?
<u>By</u><u> </u><u>using</u><u> </u><u>Pythagoras</u><u> </u><u>law</u>
h²=p²+b²
h²=6²+8²
h=√100
h=10cm
<u>So</u><u> </u><u>another</u><u> </u><u>side's</u><u> </u><u>length</u><u> </u><u>is</u><u> </u><u>1</u><u>0</u><u>c</u><u>m</u>
<u>Exercise</u><u> </u><u>2</u><u>:</u>
base [b]=6m
perpendicular [p]=bm
hypotenuse [h]=8m
By using Pythagoras law
h²=p²+b²
8²=b²+6²
b²=8²-6²
b=√28=2√7 0r 5.29 or 5.3
So height of kite is√<u>28</u><u>o</u><u>r</u><u> </u><u>2√7 0r 5.29 or 5.3 m</u>
