Answer:
√27
Step-by-step explanation:
The triangles of the pyramid are equilateral triangles with sides of 6''.
Dividing a triangle into two equal parts we get two congruent right triangles, with a hypotenuse of 6'', one leg of 3'', and the other leg is the slant height (s). From Pythagorean theorem:
3² + s² = 6²
s² = 6² - 3²
s = √27
Answer:
22
Step-by-step explanation:
-4(-5)+2
20+2
22
Answer:
Step-by-step explanation:
You can simplify this by collecting the like terms. The only like terms are the pair 2x and 18 x
2x-18x = -16x
Now, put them back together,
-16x + 14y-19
First ordered pair: (3,-7)
y=2/3x-5
-7=2/3-5
false
Ordered pair #2: (7.5,0)
y=2/3x-5
0=5-5
true
Ordered pair #3: (0,5)
y=2/3x-5
5=0-5
false
Ordered pair #4: (6,1)
y=2/3x-5
1=4-5
false
the answer to this question is the second option
