Answer:
the solution of the equation is: 
Step-by-step explanation:
we are given the expression as 
=
we will use the number line rule for inequalities(first by making the coefficients of x positive then taking the roots on the number line and depending on the sign in the equation we start taking alternate signs and depending on the inequality take the desired region)
we get
.
Answer:
Using the equation below just add like terms:
P=a+b+c+d
5x+3x+x+4x
=13x
-2+1+3
=2
13x+2
A
Area of a circle is π*r²
sub what we're given
49π= πr²
49π= π*r²
r²= 49π/π
r²=49
r=7
The diameter is twice the radius therefore the diameter is 14 units
1/5 depending on what you mean by the question you stated.
