Answer:
x (11 unit) is the longest side
Step-by-step explanation:
Given:
Sides;
7, x, and x−1
Perimeter = 28
Find:
Longest side
Computation:
Perimeter = sum of all sides
So,
7 + x + (x -1) = 28
2x + 6 = 28
x = 11
So,
x -1 = 11 - 1 = 10 unit
x (11 unit) is the longest side

see below
Step-by-step explanation:
1) 6(x + 1)+ 5 = 35
Distribute
6x+6 +5 = 35
Combine like terms
6x+11 =35
Subtract 11
6x+11-11=35-11
6x = 24
Divide by 6
6x/6 =24/6
x = 4
2) 0.7(x - 2) = 0.3
Distribute
.7x -1.4 = .3
Add 1.4 to each side
.7x-1.4+1.4 = .3+1.4
.7x = 1.7
Divide each side by .7
.7x/.7 = 1.7/.7
x = 17/7 = 2.482571429
3) 7(4x + 9) - 13 = 87
Distribute
28x +63 -13 = 87
Combine like terms
28x +50 = 87
Subtract 50 from each side
28x +50-50 =87-50
28x=37
Divide each side by 28
28x/28 = 37/28
x = 37/28 = 1 9/28
4) 0.25(3 - x) = 0.375
Distribute
.75 -.25x = .375
Subtract .75 from each side
.75-.75 -.25x = .375-.75
-.25x = -.375
Divide each side by -.25
-.25x/-.25 = -.375/-.25
x =1.5
Answer:
The constant polynomial whose coefficients are all equal to 0. The corresponding polynomial function is the constant function with value 0, also called the zero map. The zero polynomial is the additive identity of the additive group of polynomials. ... In the Wolfram Language, Exponent[0, x] returns -Infinity.
<u>It has no nonzero terms, and so, strictly speaking, it has no degree either.</u>
Answer:
D.
Step-by-step explanation:
The length of the unmarked side of the triangle is found by using Pythagoras:
x sqrt (10^2 - 6^2)
= sqrt 64
= 8.
The length of the curved part = 1/2 * pi * 10 = 5pi
Perimeter = 8 + 6 + 5pi
= 14 + 5pi
2x2x7x7
or
2^2x7^2
