Answer:
No, 4x - 12 ≠ 4x + 6
Step-by-step explanation:
<u>Step 1: Distribute both expressions</u>
4(x - 3)
(4 * x) + (4 * -3)
(4x) + (-12)
4x - 12
6x - 2(x - 3)
6x - (2 * x) - (2 * -3)
6x - (2x) - (-6)
6x - 2x + 6
4x + 6
Answer: No, 4x - 12 ≠ 4x + 6
Answer:
Just kidding
Step-by-step explanation:
I dont know
What i don't understand sorry I couldn't help because im only in 5th grade im sorry
If BC is parallel to DE then ∠D ≅ ∠B and ∠E ≅ ∠C. Therefore
ΔABC is similar to ΔADE.
The sides of smaller triangle are in proportion with sides of bigger triangle.
Therefore we have the equation:
We have AC = x, AE = x + 15, AB = 8, AD = 8 + 10 = 18.
Substitute:
<em>cross multiply</em>
<em>use distributive property a(b + c) = ab + ac</em>
<em>subtract 8x from both sides</em>
<em>divide both sides by 10</em>
<h2>Answer: AC = 12</h2>
