Answer:
125 units
Step-by-step explanation:
area o/ a rectangle=l*w
w=5
l=5w=5*5=25
a=5*25=125
He needs at least 2 gallons of the stain; though he will not use all of the second gallon
Answer:
8.2
Step-by-step explanation:
-7.2 to -7.2 is 0
-9.3 to -1.1 is 8.2
Pythagorean theorem is a^2+b^2=c^2
0^2=0
8.2^2=67.24
0+67.24=0
√67.24=8.2
The distance between the to points is 8.2
Answer:
Θ = 18.2°
Step-by-step explanation:
Using the law of sines in the triangle
= ( cross- multiply )
8 × sinΘ = 5sin30° ( divide both sides by 8 )
sinΘ = = 0.3125
Θ = (0.3125) ≈ 18.2° ( nearest tenth )
(x+3)^2 - x^2 - 3x - 7 is the correct pattern, though it is not simplified.
