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
Answer:
x≤0 ⇒|x-3|+5|x| = -6x + 3
0≤x≤3 ⇒ |x-3|+5|x| = 4x + 3
x≥3 ⇒ |x-3|+5|x| = 6x - 3

Answer:
38.60mm
Step-by-step explanation:
Step one:
Given data
We are given that the dimension of the triangles are length 23 mm and 31 mm
Let us assume that the triangle is a right angle triangle
Step two:
Applying the Pythagoras theorem we can find the third as

square both sides
z= √ 1490
z= 38.60mm
Hence a possible dimension of the third side is 38.60mm
