Answer:
Surface area of the composite figure = 508cm²
Step-by-step explanation:
Composite figures :- A composite shape is a 2D shape that is made from a combination of other basic 2D shapes and polygons. These shapes include squares, rectangles, triangles, circles.
Surface area of cuboid = 2(LB + LH + BH)
There are 2 cuboids in the question therefore solving them separately,
- For bigger cuboid
L = 12cm
B = 2cm
H = 10cm
putting these values in the above formula,
SA of bigger cuboid = 2(12×2 + 12×10 + 2×10)
SA = 328cm²
- For smaller cuboid
L = 8cm
B =3cm
H = 6cm
SA = 2(8×3 + 8×6 + 3×6)
SA = 2×90
SA = 180cm²
now surface area of whole figure,
SA of bigger cuboid + SA of smaller cuboid
328cm² + 180cm²
508cm² answer

Answers: m = 0 or m = -9</h3>
Work Shown:
m^2+9m=0
m(m+9)=0
m = 0 or m+9 = 0
m = 0 or m = -9

Answer: y= -1/4
Step-by-step explanation: _4y+8=9
-4Y=1 subtract the 8 (-8) from both sides
divide 4 by both sides and get -1/4

Answer:
4 1/2 cups of flour, 2 1/4 cups of sugar, 1 cup of brown sugar
Step-by-step explanation:
1 1/2 cups flour:3/4 cup of white sugar:1/3brown sugar yields 6 servings. So multiply each amount in the ratio by 3 for 18 servings
