Answer:
The congruence statement tells you that both angle B and angle E are equal, since the triangles are identical!
Step-by-step explanation:
We want to set the equations equal to each other.
2x+31=7x-24
We need to isolate our variable, which is X.
1. Add 24 to both sides.
New Equation: 2x+55=7x
2. Subtract 2x from both sides.
New Equation: 55=5x
3. Divide by 5 from both sides so X is alone!
New Equation: x=11
Enough said! :D
let y = x^2
4y^2 -21y + 20 = 0
solve for y
then substitute back in to get x
Answer: {y/y>-4}
Step-by-step explanation:
Answer: B and D
Step-by-step explanation:
A. States that the length of AB is -3. No, it should be 3. So that is incorrect.
B. States that the absolute value of 6-1 is the length of BC. It is 5. That is correct.
C. AB + AC = 3+8 = 11. BC is 5. That is incorrect.
D. AB + BC = AC. 3+5= 8. AC is 8. That is correct.
E. The length is not 6. It is 5. That is incorrect.
Hope that helps!
