79 divided by 10= 7
7x10= 70
79-70=9
Put a 0 beside the nine
Put the decimal beside the 7
10x9=90
90-90=0
Ur answer is 7.9
The correct answers is 0.66 or .66
Answer:
well if you're looking for angles then
angle ADB = 30°
angle CBD = 80°
angle CDB = 120°
but they asked to classify triangle ADC ,whose measurements are 90° , 40° and 50° ...so of they're asking what type of triangle then it is a right angled triangle.
Answer:
12m^2 - 9m -30
Step-by-step explanation:
So rewrite the equation to this:
4m * 3m
4m * -6
5 * 3m
5 * -6
Now solve:
4m * 3m = 12m^2
4m * -6 = -24m
5 * 3m = 15m
5 * -6 = -30
Now add them together in order:
12m^2 - 24m + 15m - 30
Simplify -24m and 15m:
12m^2 - 9m -30
Thus
12m^2 - 9m -30 is the answer
Hope this helps!
