Answer:
17
Step-by-step explanation:
6ft and 2 in === 74 in
4ft and 9 in === 57 in
74-57 = 17 in
Answer:
20.32
Step-by-step explanation:
Multiply the number of inches by 2.54 to get centimeters. In this case 8 times 2.54 = 20.32.
Answer:
24 2/5ft
Step-by-step explanation:
add all the sides together.
4ft x 2
3ft x 2
10 2/5 x 1
=
24 2/5
Step-by-step explanation:
a) 2x(3x + 1)(4 - 2x) = 0
=> 2x = 0 (or) 3x + 1 = 0 (or) 4 - 2x = 0
=> x = 0 (or) x = -1/3 (or) x = 2
b) x²(2x + 1)(x - 3) = 0
=> x²=0 (or) 2x + 1=0 (or) x - 3=0
=> x = 0 (or) x = -1/2 (or) x = 3
Hope you've understood the solutions.
Answer:
Step-by-step explanation:
Let's start by solving the first inequality:
3n+4 ≤ 19 ⇒ n ≤ 3
The second inequality is the following:
(10n)/(n²) > 1
So we solve also that:
(10n)/(n²)-1<0
(10n-n²)/(n²)<0
Numerator: 10n-n² > 0 ⇒ n²-10n < 0 ⇒ n(n-10) < 0 ⇒ 0<n<10
Denominator: n² > 0 ∀n - {0}
We draw the real axis and find out that the inequality is verified for:
n > 10
Now we make a system of inequalities and see when the first inequality and the second are verified:
n ≤ 3
n > 10
No n ∈ R satisfies this system of inequalities.
It's a weird result. Please check my work and tell me where I made a mistake.
