This is like property of a parallelogram you have to do is basically follow its properties which is opposite sides are congruent
so we solve like this

subtract -3 on each side one is canceled since its equal to zero
and other is -3-5= -8

now subtract -3 on each side
-3x-x is -4 so,
-4x=8
divide its equal to 2
X=2
Hope it helps! have an awesome day you should probably study the properties of parallelogram
Got this from a quizlet
the answers B : <B~=<Y
ABC~ZYX by the SAS similarity theorem.
Hey there!
3/7 is needed for 1 cake
If she needs to make 42 cakes, then multiply the amount for 1 by 42
42 × 3/7 = 126/7 = 18
She needs 18 kilograms of flour to make 42 cakes
Hope this helps :)
Ratios of Area of the two squares = 25:9
So then let the areas be A1 = 25A and A2 = 9A, A is common element
Side of the smaller area S2 = 30 meters
Area of the smaller square A2 = 30 x 30 = 900
We have area of smaller square as 9A = 900 => A = 100
Area of the large square = 25A = 25 x 100 = 2500.
Hence S1^2 = 2500 => S1 = 50 meters which is 20 meters longer than the
side of the smaller square.
