Answer:
W=7 L= 16
Step-by-step explanation:
you start off with
P=2L+2W (the equation to find perimeter)
the equation gives you the perimeter = 46
so you plug that in
46=2L +2W
then it says the length IS (which also means equals) 9 plus the width
so you then get another equation:
L=9+W
you take that and plus it into the first equation/ substitute the new equation for L in the first equation
46=2(9+W)+2W
you solve that and get
w=7
you plus the 7 in for the w
L=9+7 = 1
W=7 L=16
Two complementary angles sum is 90 degrees.
Angle 1 = x
Angle 2 = 2x ( two times angle 1)
Equation: x + 2x = 90
Solve:
Combine like terms:
3x = 90
Divide both sides by 3:
X = 90/3
X = 30
Angle 1= 30
Angle 2 = 60
Answer:
-6<x<0
- -
Step-by-step explanation:
make them less than or equal to signs, I don't know how to do that on a computer, I hope I am correct
point one on the left is -6, point 2 on the right is 0 (in terms of the x-axis, that's what domain is )
when there is arrows in the graph, the x/y is always in the middle.
Good luck! Hope I'm not late!
7(2)+7(5) {using distributive property}
14+35 {7 multiplied by 2 gives 14 and 7 multiplied by 5 gives 35}
49 {therefore 35+14 gives 49}
<span>the equation -2x² + 5x -3=0, we notice that the sum of the coefficient equals 0, -2+5-3=0, if such a case happens, the solution of the previous equation will be, x=1 (always) and x= c/a, a=-2, and c=-3, so x=-3/-2, finally, the answer is: the 2 in the denominator should be -2</span>
