ayy I gotchuu
Step-by-step explanation:
theres gonna be two solutions
a negative then positive
positive:
|3x - 9| = 12
3x-9=12
3x=21
x=7
negative:
3x-9=-12
3x=-3
x=-1
Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to determine that RQ² + PR² = PQ².
<h3>What is Pythagorean theorem?</h3>
Pythagorean theorem is a mathematical expression in Euclidean geometry that can be used to solve for any of the three (3) side lengths of a right triangle.
Mathematically, Pythagorean's theorem is given by this formula:
x² + y² = z²
Triangle PQR is given to be a right triangle, so the Pythagorean theorem can be used to determine that RQ² + PR² = PQ². It is given that x² + y² = z² in triangle ABC, so z² = PQ² or AB = PQ.
The above information shows that the triangles are congruent because their three (3) sides are congruent. Therefore, to show that triangle PQR is a right triangle, we can use corresponding parts of the congruent triangles to show that PQ = AB, PR = AC and QR = BC.

Answer:
1) 0.4y + 20
2) 1.8h + 3
Step-by-step explanation:
1) 4(0.1y + 5) = 0.4y + 20
Multiply (4) to (0.1y) and then multiply (4) to (+5).
2) 0.6(3h + 5) = 1.8h + 3
Multiply (0.6) to (3h) and then multiply (0.6) to (+5).
