Answer:
When the lines are parallel, there are no solutions, and sometimes the two equations will graph as the same line, in which case we have an infinite number of solutions.
Step-by-step explanation:
Answer:
The other sides of the square are
8x+12+16+8x,(8x+8x)+(12+16) and 16x+28
Step-by-step explanation:
Square:
- The all sides of a square equal.
- The sum of four angles is 360°.
- The diagonals bisect each other.
- The length of diagonals are equal.
Distributive property:
a(b+c)= ab+ac
Commutative property:
a+b= b+a
Like terms:
Like terms are terms that have the same variables and the power of the variable also same.
Given the length of the side is
=4(2x+3)+16+8x
=4.2x+4.3+16+8x [ Apply distributive property]
=8x+12+16+8x
=(8x+8x)+(12+16) [ separating like terms]
=16x+28 [Adding like terms]
The other sides of the square are
8x+12+16+8x,(8x+8x)+(12+16) and 16x+28
We can proceed in solving the problem since all information are given such as 2*4*5costheta.
we have a=4, b=5, and C=theta
let us solve for "c" using Pythagorean
c²=a²+b²
c²=4²+5²
c=6.4
Solving for theta or C
c²=a²+b²-2abcosC
6.4²=4²+5²-2*4*5*cosC
C=90
360 kilometers is 24 percent of 1500 kilometers. Hope it help!
Answer:
x-9 = 9 x-9 = -9
Step-by-step explanation:
(x - 9)^2 = 81
Take the square root of both sides
sqrt((x - 9)^2) = ±sqrt(81)
x-9 = ±9
x-9 = 9 x-9 = -9
