Answer:
B) 1
Step-by-step explanation:
We can see that the equation has only one real solution since both sides only intersect at that one point (4,3).
Answer:
27.37 and 9.18
Step-by-step explanation:
(4)
Using the cosine ratio in the right triangle
cos64° = 
= 
( multiply both sides by x )
x × cos64° = 12 ( divide both sides by cos64° )
x = 
≈ 27.37 ( to the nearest hundredth )
(5)
Using the sine ratio in the right triangle
sin35° = 
= 
( multiply both sides by 16 )
16 × sin35° = x , then
x ≈ 9.18 ( to the nearest hundredth )
Answer:
(x+6) feet, 110sq ft
Step-by-step explanation:
Area = width * length = something * (x + 7)
Width = (x+6) as 6 and 7 add to 13 and times to 42.
To confirm expand (x+6)(x+7)=x^2+6x+7x+42=x^2+13x+42
(x+6) feet
4^2+13(4)+42=16+52+42=110 sqft
