Answer: The width of the rectangle is 10.2 inches, the perimeter is 71.4 inches, the area is 260.1 inches.
Step-by-step explanation:
25.5/5=5.1
5.1*2=10.2
The width is 10.2 inches
25.5*2+10.2*2=71.4
The perimeter is 71.4 inches
20.5*10.2=260.1
The area is 260.1
Answer:
Yusuf = 37.5
Ajay = 13.5
Step-by-step explanation:
Lets say.. Yusuf = y and ajay = a
y = 24+a (since yusuf is 24 years older than ajay)
5 years before, the sum of their ages was 41 so subtract 5 from y and a and add the two.
(y-5)+(a-5)=41
We already have defined y in terms of a (y =24+a) so we substitute that in for y.
(24+a-5)+(a-5)= 41
24-5 = 19
19+a+a-5=41
a+a = 2a
2a+19-5 = 41
19-5 = 14
2a+14 = 41
subtract 14 from both sides
2a=27
a=13.5
substitute that in y=24+a
y=24+13.5
y=37.5
lets check these answers.
(37.5-5)+(13.5-5)= 41
37.5-5 = 32.5 and 13.5-5= 8.5
32.5+8.5=41??
Correct!
Answer:
10
x^4 - 8x^5
Explanation:
To write a polynomial in standard form, simplify and then arrange the terms in descending order. Ex. ax^2+ax+c
Then you would simplify
−2 x−5(x^2x^2)−2x4(x^2x^3)
Simplify each term
= 10
x^4 - 8x^5
Answer: I think it’s A because 8x5=40
