Solve for the variable: 3(q-5)=2(q+5)
Answers
a(b+c)=ab+ac or
a(b-c)=ab-ac
so
3(q-5)=3q-15
2(q+5)=2q+10
3q-15=2q+10
minus 2q from both sides
q-15=10
add 15 to both sides
q=25

Answers
a₁ - arm the small square
a₂ - larger side of the square
2a₁ = a₂ we put into the equation 2
(a₁)² + (a₂)² = 45cm²
2a₁ = a₂
(a₁)² + (2a₁)² = 45cm²
(a₁)² + 4(a₁)² = 45cm²
5(a₁)² = 45cm²
(a₁)² = 9cm²
a₁ = √(9cm²) = 3cm
a₂ = 2a₁ = 2*3cm = 6cm
A₁ = (a₁)² = (3cm)² = 9cm²
A₂ = (a₂)² = (6cm)² = 36cm²
A₁ + A₂ = 9cm² + 36cm² = 45cm²
