Answer:
(x+1)(x+1)(2x−5)(x^2−4x+5)
Step-by-step explanation:
2x^5−9x^4+6x^3+22x^2−20x−25
2x^5−9x^4+6x^3+22x^2−20x−25
=(x+1)(x+1)(2x−5)(x2−4x+5)
239.99 x 75%(75/100) ~ $180
$180 x 90%(90/100) = $162
Answer: 220 cm squared
Step-by-step explanation: Formula for surface area of a prism...
S = 2(lw + lh + wh) l = 5 w = 10 h = 4
so
lw is 5 x 10 = 50
lh is 5 x 4 = 20
wh is 10 x 4 = 40
plug these into equation...
S = 2(50 + 20 + 40)
S = 2(110)
S = 220
I honestly have the same question help!!
Answer:
At 5% , $300 was invested
At 15%, $4,700 was invested
Step-by-step explanation:
Let the amount invested at 5% be $x and the amount invested at 15% be $y
x + y = 5000 ••••••(i)
Let’s work with the interest;
5% of x + 15% of y = 720
0.05x + 0.15y = 720 •••••(ii)
From i;
x = 5000-y
Insert this into ii
0.05(5000-y) + 0.15y = 720
= 250 - 0.05y + 0.15y = 720
250 + 0.1y = 720
0.1y = 720-250
0.1y = 470
y = 470/0.1
y = $4700
x = 5000-y
x = 5000-4700 = $300
