Answer:
3(c+4)
Step-by-step explanation:
It would usually be 3 x 4, but since there is a variable, it can`t be multiplied (unless you know what the value of the variable is). Thus the expression is 3(c+4).
Answer:
56x+12y-10.6
Step-by-step explanation:
The multiple choice answer is B.
Yes, of course there'd be white
Step-by-step explanation:
=3.0625/ 1
=30625/10000
(multiply top until the decimal goes. and have to multiply by the same number bottom also, here have multiplied by 10000 both bottom and top)
=6125/ 2000
=49/16 (simplify the both bottom and top)
180 ÷3 = 60 ° (angles on a straight line equals to 180 ° )
a+b+60 =180°
a+ b= 180 ° - 60° = 120°
(a+b) are 2 variables
so 120 ÷2 =60 °
therefore a and b =60 °
c +b+ 60° = 180° ( co - interior angles are supplementary angles )
c+60° +60° =180°
c +120° =180°
c =180°-120°
c=60 °
d=60° (alternate angles are equal )
or
c+b+d=180°
60° +60° + d = 180°
d=180°-120°
d=60°
