Answer:
Step-by-step explanation:
Property of a right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
If the length of sides of the given triangle are 7mm, 14mm and 15mm.
(15)² = (7)² + (14)²
225 = 49 + 196
225 = 245
False
Therefore, the given triangle is not a right triangle.
This is a working backwards problem. You know he has $35 at the end. Before he gave his brother $5, he would have $40, which is half of what he had before he bought the clothes, so he would have had $80. Before he spent the $40 on shoes, he would have had $120, so the answer is $120.
Answer:
the domain is : D = ]-∞ , -5[ U ]-5 , -3[ U ]-3 , +∞[
Step-by-step explanation:
hello :
f(x) = 9x/(x+5)(x+3)
f exist for : (x+5)(x+3) ≠ 0
(x+5)(x+3)=0
x+5=0 or x+3=0 means : x= - 5 or x= -3
the domain is : D = ]-∞ , -5[ U ]-5 , -3[ U ]-3 , +∞[
