Answer:
784 cm
Step-by-step explanation:
7 x 7 = 49
4 x 4 = 16
49 x 16 = 784
Answer:
Step-by-step explanation:
-2(3x + 12y - 5 - 17x - 16y + 4) =.....combine like terms
-2(-14x - 4y - 1) =

Answer:
c) 4
The value of z= 4
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given equations are
3x - y =16 .. . (i)
3x -4z =2 .. . (ii)
2x +y = 14 .. .(iii)
solving (i) and (ii) equations , we get
Adding (i) and (ii)
3 x -y + 2x +y = 16 +14
5 x = 30
x = 6
<u><em>step(ii):-</em></u>
Substitute 'x' =6 in equation (i), we get
3(6) -y =16
18 - 16 =y
y = 2
x =6 and y =2
substitute x=6 in equation (ii) , we get
3 (6) - 4 z = 2
18 - 2 = 4 z
16 = 4 z
z = 4
<u><em>Final answer:-</em></u>
x = 6 , y = 2 and z =4
Answer:
3 Km
Step-by-step explanation:
The 4 sides of a square are congruent , then
perimeter = 4 × 
( cancel the 4 on numerator and denominator )
perimeter = 3 Km
