Answer:
Step-by-step explanation:
Call high street is a, using Pythagorean Theorem we have:
x^2 = 4 + a^2
b^2 = a^2 + 36
64 = x^2 + b^2
so we have x^2 = 16, a^2 = 12, b^2 = 48
so x= 4
Answer:
the answer is A- B/3 or B divided by 3
Step-by-step explanation:
X^2 + 9x -10 = (x -1)(x +10) = (x +(-1)) (x + 10)
p = -1 and q = 10
answer is A.
Answer:
x = 11.25
Step-by-step explanation:
-6 = 0.8x - 15
Add 15 to both sides;
-6 + 15 = 0.8x - 15 + 15
9 = 0.8x
Divide both sides by 0.8;
x = 11.25
