Step-by-step explanation:
bruh did u have hentoi as your pic
So remember that the pythagorean theorem is a^2+b^2=c^2
c=18
legnth is 3 more than width
l=3+w
a=3+b
subsitute
(3+b)^2+b^2=18^2
expand
9+6b+b^2+b^2=324
subbtract 9 from both sides
6b+2b^2=313
subtract 313 from both sides
2b^2+6b-313=0
factor
use quadratic formula and get
b=11.1
subsitute
a=3+b
a=3+11.1
a=14.1
answer is 14.1 ft by 11.1 ft
Answer:
a = 1 , b = 0 and c = 5
Step-by-step explanation:
The given matrix are,
[2 1 0] X 1 -1 2 = [a b c]
-1 -2 1
0 1 1
a = (2*1) + (1*-1) +(0*0) = 2 -1 + 0 = 1
b = (2*-1) + (1*-2) +(0*1) =-2 -2 + 0 = 0
c = (2*2) + (1*1) +(0*1) = 4 +1 + 0 = 5
Therefore the values of a,b, and c are
a= 1 , b = 0 and c = 5
Answer:
39 units²
Step-by-step explanation:
the perimeter of triangle =
7+6+9.22 = 22.22 cm
=> the radius oh the circle =
r = c/2π = 22.22/ 2×3.14
= 3.54
so, the area of the circle = π.r²
= 3.14 ×(3.54)²
= 3.14 × 12.53
= 39.34 => 39 units²
