Answer:
x=5
Step-by-step explanation:
9x^2 - 2x + 25 = 8x^2 + 8x
9x^2-8x^2-2x-8x+25=0
x^2-6x+25=0 factorize
(x-5)(x-5)=0
x-5=0 then x=5
If we take for example 20x1.5=30 the scale factor would create an enlargement
Answer:
14°
Step-by-step explanation:
(7x-1)°+(6x-1)°=180°(sum of angles in a straight line/being linear pair)
or,7x-1°+6x-1°=180°
or,13x-2°=180°
or,13x=182°
or,x=182°/13
or,x=14°
