Using the net, we see that the square pyramid breaks down to 4 equivalent triangles and a square. We can use this formula to solve for the surface area:
Sa=A(square)+4*A(triangle)
The formula for the area of a square is
A=l*w
A=7*7
A=49mm²
The formula for the area of a triangle is:
A=1/2b*h
A=1/2*7*12.2
A=42.7mm²
Now that we have the individual areas of the shapes, we can solve for the surface area.
Sa=A(square)+4*A(triangle)
Sa=49mm²+4*42.7mm²
Sa=49mm²+170.8mm²
Sa=219.8mm²
Answer=219.8mm²
ANSWER=A
4(y+4)-7y
Use the distributive property.
a(b+c)= ab+ac
4*y= 4y
4*4= 16
4y+16-7y
4y-7y= -3y
-3y+16 <----- simplified expression
I hope this helps!

$139 - $121 = $18
(139-121) / 4 = b
BTW
he would only be able to buy 4 buns because he only has $18 dollars left and 4 buns x 4 dollars = a total cost of 16 dollars so
Luke would only be able to buy 4 buns and have $2 left over
Answer:
No, they are not.
Step-by-step explanation:
Answer:
The third figure is the answer (Look to the attached figure
Step-by-step explanation:
* The point of symmetry means
- If a figure or graph can be rotated 180° about a point P
and end up looking identical to the original, then P is a point
of symmetry
- The same distance from the central point
but in the opposite direction.
* Lets look to the four answers
- In the 3rd figure first line up can be rotated 180° about a point P
and end up looking identical to the second line down, then P
is a point of symmetry
- The same distance from the point p
but in the opposite direction.
* The figure show the answer
