Hi there!
13y² + 10y - 3 = 5y²
Begin by moving all terms to one side:
13y² + 10y - 3 - 5y² = 0
Combine like terms:
8y² + 10y - 3 = 0
Factor using the guess-and-check method.
(4y - 1)(2y + 3) = 0
Set each factor equal to 0 to find the solutions:
4y - 1 = 0
4y = 1
y = 1/4
2y + 3 = 0
2y = -3
y = -3/2
The size ot the "larger square" is 5cm
Answer:
Option C - 65°
Step-by-step explanation:
Since the side lengths of this triangle are equal this triangle is an isosceles:
Because the triangle is an isosceles the base angles are equal so
∠G = ∠F = 65°
Answer:
B
Step-by-step explanation:
R + 3 = 2
First, subtract 3 from both sides. / Your problem should look like: r = 2 - 3
Second, simplify 2 - 3 to -1. / Your problem should look like: r = -1
Answer: r = -1
