There are 2 triangles once u slice in half so triangles is the right answer
Answer:
-9x + 3
Step-by-step explanation:
You would distribute first.
− ( x + 3 ) − 2 ( 4x − 3 ) → -x − 3 − 8x + 6
(If you see a negative sign in front of a parenthesis without a number, its usually a negative 1)
From there, you would combine like terms.
-x − 3 − 8x + 6 → -9x + 3
72 and 50 are the answer for 12 times 6 and 10 times 5
Answer:
The distributive property of multiplication over addition: Multiplying a sum by a number is the same as multiplying each addend by the number and then adding the products. ... The distributive property of multiplication over subtraction.

</u>
Step-by-step explanation:
<u>Step 1: Identify</u>
Angle θ = 50°
Opposite Leg = 7
Adjacent Leg = BC
<u>Step 2: Solve for BC</u>
- Substitute in variables [tangent]: tan50° = 7/AC
- [Multiplication Property of Equality] Multiply AC on both sides: ACtan50° = 7
- [Division Property of Equality] Isolate AC: AC = 7/tan50°
- Evaluate: AC = 5.8737
- Round: AC ≈ 5.87
