C equals eight because it is adding three
1/4 + 1/4= 1/2
There are 2/4 in 1/2.
Hope this helps! :)
The surface area of a rectangular prism is the sum of the areas of its faces added together. From the picture, we can see that the prism is constructed of 4 faces that measure 7 cm by 9 cm and 2 faces that measure 7 cm by 7 cm.
The area of one 7 cm by 9 cm face is 63 cm². Together, all four of the faces add up to 252 cm².
The area of one 7 cm by 7 cm face is 49 cm². Together, the two faces add up to 98 cm².
Using these areas, we can say that the total surface area of the prism would be 252 cm² added to 98 cm², or 350 cm².
Answer:
y=4
Step-by-step explanation:
9y=36
first divide both sides by 9 (9y/9) and (36/9)
y=4
Now test that it is correct by replacing y with 4
9(4)=36
Indeed!
Distance equals end minus start
(-7,-7)-(5,9)=
(-7-5,-7-9)=(-12,-16)
(-12,-16) gives us the distance point coordinates. Now to find the magnitude we can take sqrt((-12)^2+(-16)^2)=20
So the distance between the two points is 20
