Answer:
12x -2 = 22
12x = 22 +2
12x = 24
x = 24/12
x= 2
therefore, the vale of x =2.
Answer:
704 cm
Step-by-step explanation:
The two triangles are 8x12=96 and since there are two triangles 96x2=192.
Next you do the top and bottom rectangles 10x16=160 and the two rectangles are the same size so 160x2=320.
Now you do the middle rectangle 16x12=192.
Now you add all the areas together 192+320=512+192=704cm.
So the answer is 704 cm!
Answer:
Algebra Review: x=-4, r =5
Step-by-step explanation:
Use distributive prop;
-3x-6=6
then add 6 to both sides to get x by itself
you get -3x=12
divide both sides by -3
you get x=-4
Again do distributive prop.
-12r+24=-36
trying to get r by itself, so subtract 24 on both sides
you get: -12r=-60
then divide -12 both sides to get r by itself and you get r=5
Pythageron Theorem:
which is a^2+b^2=c^2
a=3, b=7 and c=C^2 (this is always the long side)
so then we get 3^2+7^2=c^2
9+49=c^2
opposite of sqaring is rooting
so we get sqare root of 58 or 7.6
I'm sorry I can't help you with the angles, I would suggest looking it up and Khan Acadamy is a good resource. Good Luck!
