Answer:
D)
Step-by-step explanation:
5x5+5=30
8x9+7=79
24x3+28=100
When 1250^3/4 is written in simplest radical form the vale 2 remains under the radical
Hey there :)
The perimeter formula of a trapezium is:
P = a + b + c + d ( adding all sides )
Perimeter is given : P = 17z³ + 60z² + 2z - 5
Part A :
Total lengths of sides 1, 2 and 3 will be just adding the given lengths :
1 → 16z² - 4z + 2
2 → 7z² - 2z + 21
3 → 18z² - 3z + 2
side 1 + side 2 + side 3
( 16z² - 4z + 2 ) + ( 7z² - 2z + 21 ) + ( 18z² - 3z + 2 )
Combine like terms together:
16z² + 7z² + 18z² - 4z - 2z - 3z + 2 +21 + 2
41z² - 9z + 25Part B:
Length of 4th side will be the total perimeter minus the total length of sides 1, 2 and 3:
( 17z³ + 60z² + 2z - 5 ) - ( 41z² - 9z + 25 )
Combine like terms
17z³ + 60z² - 41z² + 2z + 9z - 5 - 25
17z³ + 19z² + 11z - 30
Part C:
Addition of polynomials result in polynomials as well as subtraction of polynomials result in polynomials.
Therefore, this polynomial is closed under addition and subtraction.
Answer:
X= -5
Step-by-step explanation:
do you need steps?
5x +7/2 = 3x/2 -14
10x+7/2 = 3x-28/2
2(10x+7) = 2(3x-28)
20x +14 = 6x - 56
20x -6x = -56 - (14)
14x = -70
x = -70/14
x = -5
