Answer:
302 cm²
Step-by-step explanation:
To find the surface area of the figure, find the area of each face and add them together.
<u>The cube</u>
There are 9 faces for the 2 cubes on top of the blue prism. Each face measures as 2cm by 2 cm. The area of one face is A = 2*2 = 4 cm². Since there are 9 faces, the surface area of the cubes is 9*4 = 36 cm².
<u>The rectangular prism</u>
There are 6 faces for the blue prism. Four of the faces measure 11 cm by 5 cm. Two of the faces measure 5cm by 5 cm. Find the area by multiplying each face's measurements.
11*5 = 55
Four faces: 4*55 = 220 cm²
5*5 = 25
Two faces: 2*25 = 50 cm²
All together the surface area of the figure is 36 + 220 + 50 = 306.
However notice that the cube sits on top of the blue prism and covers up a portion of the face. The area it covers is 4 cm². Subtract 306 - 4 = 302.

Find a solution
To do this, we assume a value for x, then solve for y.
Let x = 1
Substitute 1 for x in
Hence, a solution is:
Answer:
n=0.2
Step-by-step explanation:
Yay
so
this is going to be
(x-h)^2=4p(y-k)
(h,k) is the vertex
p is the distance from the vertex to the focus and the vertex to directix
half of the distance between directix and focus is p
if the directix is above the focus, p is negative
if the directix is below the focus, p is positive
so
we see
y=15/8 is the directix
focus is above directix (p is positive)
it is 2/8 or 1/4 above it
so
half of 1/4 is 1/8
p=1/8
the vertex is 1/8 below vertex so it is it at (-4,16/8) or (-4,2)
the equation is
(x-(-4))^2=4(1/8)(y-2) or
(x+4)^2=4(1/8)(y-2) is the equation
Brooke is 8 years old! This is what I did⬇️
5x2=10. (In 5 yrs 10 will add to the sum of their age.
29-10=19. (The sum of their ages right now is 19)
11 + 8 = 19 ( 11 is 3 more than 8 and it equals their ages together)
Brooke:8
Samantha:11
