-4x – 2y=-12<br> 4x + 8y=-24<br> Solve each system by elimination
kirza4 [7]

Answer:

x = 6 and y = - 6

Step-by-step explanation:

- 4 x - 2 y = -12.......equ No 1

 4 x +  8y = - 24.......equ No 2

Adding equ No 1 and equ No 2

6 y = - 36

∴ y = - 6

substitute y = - 6 in equ No 2

4 x + 8 y = -24

4 x + 8 ×( -6) = - 24

4 x - 48 = -24

4 x = -24 + 48

4 x = 24

∴ x = 6

x = 6 and y = - 6

A candle is in the shape of a square pyramid. Its height is 5 cm and its slant height is 8 cm
Akimi4 [234]
Using the Pythagoras theorem

8^2 = 5^2 + x^2   where x = 1/2 length of the base

x^2 = 64-25 = 39

x = = sqrt39 = 6.24

so base length = 2*6.24 = 12.5 cm to nearest tenth
