Answer:
10 (X+1)
Step-by-step explanation:
Length = 2x + 5
Width = 3x
Perimeter of rectangle= 2(L + W)
P= 
P= 
Now, taking 5 as common
P= 
∴ Perimeter of rectangle= 
Answer:
-27
Step-by-step explanation:
(-243)^3/5
We know that a^b^c = a^ (b*c)
(-243) ^ 1/5 ^3
We know (-243) ^ 1/5 = -3
(-3) ^3 = -27
Answer:
=0.065x10−0.1
Step-by-step explanation:
(1.3x10−2)(0.05)
=(1.3x10+−2)(0.05)
=(1.3x10)(0.05)+(−2)(0.05)
=0.065x10−0.1
Answer:
22 ft
Step-by-step explanation:
Find the perimeter.
6 + 6 + 5 + 5 = 22 ft
Answer:
(0, 4 ) and (2, - 4 )
Step-by-step explanation:
(2)
3x + 4y = 16 → (1)
- 3x + 2y = 8 → (2)
Adding (1) and (2) term by term will eliminate the x- term
0 + 6y = 24
6y = 24 ( divide both sides by 6 )
y = 4
Substitute y = 4 into either of the 2 equations and solve for x
Substituting into (1)
3x + 4(4) = 16
3x + 16 = 16 ( subtract 16 from both sides )
3x = 0 , then
x = 0
solution is (0, 4 )
(3)
2x - 4y = 20 → (1)
5x + 4y = - 6 → (2)
Adding (1) and (2) term by term will eliminate the y- term
7x + 0 = 14
7x = 14 ( divide both sides by 7 )
x = 2
Substitute x = 2 into either of the 2 equations and solve for y
Substituting into (2)
5(2) + 4y = - 6
10 + 4y = - 6 ( subtract 10 from both sides )
4y = - 16 ( divide both sides by 4 )
y = - 4
solution is (2, - 4 )
