Answer:
-5/4
Step-by-step explanation:
<span>Julia is X+5
</span><span>x+x+5=31
</span>
Now we just solve the equation
2x=31-5
x=26/2
x=13 years old (Babs' age)
and we know that julia is 5 years older this gives us the conclusion that.
13+18=31
Statement:
1. RS tangent to Circle A and Circle B at points R and S
2. AR ⊥ RS, BS ⊥ RS
3. AR ║ BS
Reason:
1. Given
2. Radius ⊥ to tangent
3. 2 lines ⊥ to same line are ║
100% Correct
~Hope it helps~ :)
Answer:
A = 5x³ + 17x² - 35x - 30
Step-by-step explanation:
the shaded area (A) is calculated as
A = outer area - inner area
= (5x + 3)(x² + 4x - 10) - 3x(2x - 1) ← distribute parenthesis
= 5x³ + 20x² - 50x + 3x² + 12x - 30 - (6x² - 3x)
= 5x³ + 23x² - 38x - 30 - 6x² + 3x ← collect like terms
= 5x³ + 17x² - 35x - 30
