Answer:
A. b+2(b+2b)
b + 2b + 4b = 7b
B. 3b + b = 4b
C. 2(2b) = 4b
None of them are equal to 9b
Ok so it’s 6.93 or 7 if u wanna round it
It’s the a^2+b^2=c^2
Answer:
a) DE = 15
b) AB = 6
Step-by-step explanation:
24/8 = 3
18/3 = 6
5*3 = 15
Answer:
51
Step-by-step explanation:
y is the ten digit
and x the ones digit
y+x=6 -> x=6-y subtracted each side by y
2y+3=x
2y+3=6-y they both equal x so the equal each other
add y to both side to get rid of the y
minus 3 form both side to get rid of the 3
3y=3
y=1
plug it in
2(1)+3=x
5=x
51
I’m pretty sure it would just be sine=opposite/hypotenuse and tan=opposite/adjacent. For x it’d be: sin30=4/x . And for y it’d be: tan30= 4/y
