You multiply 5+3 and then you get the answer for it
Answer:
X = 96
Step-by-step explanation:
the out sides of triangles add up to 360 so we will find out what it adds up to now and how much is missing
130 + 134 = 264 is how much it is now but we need 360
lets see how far away we are 360 - 264 = 96
and 96 would be x
Answer:
7n+(3+2n)=30
Step-by-step explanation:
The number (n) is 3.
Step-by-step explanation:
<h2>A^2 + B^2 = C^2 </h2>
A and B are the legs of the triangles.
C is the hypotenuse.
12^2 + x^2 = 20^2
144 + x^2 = 400
-144 -144
x^2 = 256
x = 16
The length of the second leg is 16.
To know the amount of eights you want to get something that looks like ?/8. Basically, the bottom number needs multiplying by 2 (8 divided by 4 is 2). To keep the fraction accurate you multiply by 2 the top and bottom number so you get:
<span>3/4=(3x2)/(4x2)=6/8</span>
