Answer:
Part A: C
Part B: B
Part C: 15.91
Step-by-step explanation:
first round the 2 numbers by the tenths. Then round the numbers by ones(whohle number). After that, since ther are four sides we do 12.63 + 3.28 + 12.63 + 3.28 which equals to 15.91.
A (b-c)=d
ab-ac=d
ab-d=a.c
Divide both sides by a
Your answer = ab-d/a
Answer choice C
Equation is 2(3x+24)=9x+18
Answer is x=10
Bisector means it cuts it in half so ABD is the same as DBC. The whole angle is 9x+18 which is the same as doubling 3x+24 since thats half of if hence the equation 2(3x+24)=9x+18
To solve for x you have to distribute 2(3x+24) by multiplying 2 to 3x and 24
New equation is 6x+48=9x+18
Subtract 6x both sides
48=3x+18
Subtract 18 both sides
30=3x
Divide both sides by 3
10=x
Answer:
16
Step-by-step explanation:
In China, it has a formula, writing S = one-half (s·h)
The B coordinate minus the D sitting mark is s, the A coordinate minus the C coordinate is h, that is, S = one half (8 × 4) = 16
