Answer:
12 + 12 = 24
Step-by-step explanation:
P = 2L + 2W
P = 2*16 + 2W
P = 56
56 = 32 + 2W Subtract 32 from both sides
56 - 32 = 2W
24 = 2W Divide by 2
24/2 = 2W/2
12 = W
The answer you want is 2 * 12 = 24
Answer:
infinite solutions
Step-by-step explanation:
Given
x + 3 + 2x = 4 + 3x - 1 ( simplify both sides )
3x + 3 = 3x + 3
Since the equation is the same on both sides.
This indications the equation has an infinite number of solutions
7. general term of gp is given by ar^n-1
hence,4th term is given by
ar^3=15 ------(1)
ar^6=405-----(2)
equation 2/1,we get
r^3=27
so common ratio r=3
putting value of r in equation 1,
we get a=5/9
so gp upto 7 terms will be 5/9,5/3,5,15,45,135,405
8. a=3
given 4th term is -24
so ar^3=-24
substituting value of a we get r^3=-8
r^3= -2^3
so r = -2
using this x2 is ar= 3*-2=-6
x3 is ar^2= 3*4=12
11:45 - 30 = 11:15
11:15 - 1 hr: 10:15
10:15 - 50 = 9:25
her math class starts at 9:25
D
given the 2 equations
x + 2y = - 8 → (1)
- 4x + y = 5 → (2)
multiply (1) by 4
4x + 8y = - 32 → (3)
add (2) and (3) term by term to eliminate term in x
9y = - 27 ( divide both sides by 9 )
y = - 3
substitute y = - 3 in either (1) or (2) and solve for x
(1) : x - 6 = - 8 ( add 6 to both sides )
x = - 2
solution is (- 2, - 3 ) → D
