Answer:
YZ = 18.4 in
Step-by-step explanation:
The midsegment YZ is half the length of the third side VX , then
YZ = 
× 36.4 = 18.2
2x^2 + x -3 can be factorised
<span>[2x + 3][x - 1] </span>
<span>As length times width = area </span>
<span>one possible set of measurements are </span>
<span>length = [2x + 3] </span>
<span>width = [x-1] </span>
Answer:
156.25 grams
Step-by-step explanation:
Well, for starters we know that the substance decays by 2% each day and its been decaying for 34 days. Therefore, the substance has decayed by 68%
34 x 2 = 68
Hence, 50 grams is 32% because the substance has already decayed by 68%
100 - 68 = 32
So now we know 50 grams is 32%. Now we need to find how much 100% is.
50 - 32%
X - 100%
We cross multiply.
50 x 100 = 5000
And divide.
5000 / 32 = 156.25
Thus, in the beginning, there were 156.25 grams in the substance.
Hope this helps! :)
Answer: (X+6)(x-4)
Step-by-step explanation:
x^2-4x+6x-24 ==> x^2+2x-24
*Find two numbers that multiplied gives you -24 and add up to 2*
(6)(-4)= -24 6-4=2
Final result= (x+6)(x-4)
