1 and 4 will be the expression that makes the equatio. true for all values of x to prove i have done it in the picture attached in this message
The GCF of 18 and 39 is 3
The area of a triangle is 1/2 b/h. So what you do is you find base and height, multiply them together and whatever answer you got, you divide by 2.
Example:
A= 1/2 (b x h)
A= 1/2 (4 x 6)
A= 1/2 (24)
A= 12
Hope this helps!
Answer:
Subtract 4
Step-by-step explanation:
-3 - 4 = -7
-7 - 4 = -11
-11 - 4 = -15
volume of square pyramid = S^2*h/3
volume = 36
h = 3
36 = S^2 *3/3
36 = S^2
S = sqrt(36)
S = 6
length of base = 6
