Answer:
152 cm²
Step-by-step explanation:
The shaded area is calculated as
outer area - inner white area
= (12 × 18) - (8 × 8 )
= 216 - 64
= 152 cm²
Ie 32^2 - 4ac=0 so ac=256 and a+c=130
So, that means:2 equations ac=256 a+c=130 ie c=130-a
So,a(130-a)=256 so 130a -a^2=256 ie a^2-130a +256=0 (a-2)(a-128)=0
Finally,giving a= 2 or a=128 so, a=2 c=128 or a=128 c=2
Since, a>c , a=128 and c=2 ie (128,2)
The answer is 28.67 with the tax rate and total amount
Answer:
12cm^2
Step-by-step explanation:
B is triangle, so the area of B is the area of triangle.
B=ah/2, where a=6 and h=4
B=6*4/2=12 cm^2
Volume: V=Bh where h is 9cm (from picture)
V=12cm^2*9cm=108cm^3
