Answer:
7) 230mm
8) 98m
Step-by-step explanation:
7)
7x+8+6x+6+9x-4 =22x+10
if x is 10 mm, 22(10)+10 =230mm
8) perimeter of rec =2( l + w )
=2 ( 2x-5+2x+6 ) = 8x + 2
if x is 12 metres, 8(12)+2 =98m
What you do here is subtract g from f: x^2 - 5x + 8 - (x^2 -4); x^2 - 5x + 8 - x^2 + 4; Rearranging gives you x^2 - x^2 - 5x + 8 + 4 which is, simplified, -5x + 12
Answer:
Step-by-step explanation:
By collecting the like terms , we have:
5q - 3q = - 8 - 4 - 2p
2q = -12 - 2p
divide each term by 2 , we have
q = -6 - p
Answer:
1170 m²
Step-by-step explanation:
Parallelogram: 40 x 18 = 720
triangle: (50 x 18) / 2 = 450
total area: 720 + 450 = 1170
