Step-by-step explanation:
given x² = 17 → take the square root of both sides
= ±
x = ±
Answer:
3080 square inches
Step-by-step explanation:
I like to draw things out. So I drew this cooler out, with the dimensions of 26x14x16. It the cooler is 2 inches thick, I need to remove 2 inches from each side of the cooler. So I took 4 inches off of the 26 and the 14 so the length and width become 22 and 10 respectively. Then I took 2 inches off the bottom of the cooler so the 16 became 14. This gives me the new dimensions of 14x22x10.
Answer:
x=-1
Step-by-step explanation:
-2(3x-5)=4(x+3)+8
-6x+10=4(x+3)+8
-6x+10=4x+12+8
-6x+10=4x+20
-6x+10-10=4x+20-10
-6x=4x+10
-6x-4x+10-4x
-10x=10
x=-1
The term in the expansion:
T ( k+1) = n C k * A^(n-k) * B^k.
In this case: n = 11, k + 1 = 8, so k = 7.
A = x, B = - 3 y
T 8 = 11 C 7 * x^(11-7) * ( - 3 y )^7 =
=( 11 *10 * 9 * 8 * 7 * 6 * 5 ) / ( 7 * 6 * 5 * 4 * 3 * 2 * 1 )* x^4 * ( - 2,187 y^7 ) =
= 330 * ( - 2,187 ) x^4 y^7 = - 721,710 x^4 y^7
Answer: The 8th term in expansion is
5%
because 30/100 - 25/100 = 5/100
