Answer: I am sorta answering this on my alt, just move along
Step-by-step explanation:
The whole lenght is the short length 9 and the long length 18 added.
(1,3)
You plug the equation that equals y into the y value on the other equation that equals 4. Then, you plug the x value into the x on the equation that equals y. Sorry if that was confusing
<h3>Answer:</h3>
A. None of the factors were negative
because when you multiply or divide an inequality by a negative number you must flip the inequality sign.
Hope this helps you! :)
Answer:
2.7
Step-by-step explanation:
x^2=5.8*1.3=7.54
x=V7.54=2.7
Answer:
9) JK = 24.5
10) LM = 24.5
11) m∡L = 51°
12) m∡M = 129°
Step-by-step explanation:
in a parallelogram, adjacent angles are supplementary (add to 180 degrees) and are also congruent
so, ∡K = ∡M and ∡J = ∡L
since ∡'s L and M are adjacent we can add them and set them equal to 180
5z - 6 + 2z - 3 = 180
7z - 9 = 180
7z = 189
z = 27
therefore, m∡M = 5(27)-6 = 129 and m∡L = 180-129, or 51
Also in a parallelogram, opposite sides are equal; so KJ = LM and KL = JM
7x = 3x + 14
subtract 3x from each side to get:
4x = 14
x = 14/4 = 3.5
to find measure of JK, substitute 3.5 for 'x' to get (3.5)(7) = 24.5
to find measure of LM, substitute 3.5 for 'x' to get (3.5)(3)+14 = 24.5
