Answer:
x ≈ 17.3
Step-by-step explanation:
The triangles are all similar, so the side lengths are proportional.
short side / hypotenuse = x/30 = 10/x
x² = 300 . . . . . . cross multiply
x = 10√3 . . . . . . take square root
x ≈ 17.3
It should be b) from my recollection.
Answer:2x−5=−5
Add 5
to both sides of the equation.
2x=−5+5
Add −5
and 5
.
2x=0
Divide each term by 2
and simplify.
Divide each term in 2x=0
by 2
.
2x2=02
Cancel the common factor of 2

Cancel the common factor.
2
x2=02
Step-by-step explanation:
Apply the distributive property.
x⋅2+2⋅2−9=−5
Move 2
to the left of x
.
2⋅x+2⋅2−9=−5
Multiply 2
by 2

The hull speed of the Santa Monica in terms of the length, ln of the Nina Pinta is given as a√b where a = 1.34 and b = ln - 10
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
Given that:
v = 1.34√l
where l is the hull length in feet and v is the hull speed in knots.
Santa Monica has a hull length that is 10 ft shorter than that of the Nina Pinta and ln is the length of Nina. Hence:
v = 1.34√(ln - 10) = a√b
The hull speed of the Santa Monica in terms of the length, ln of the Nina Pinta is given as a√b where a = 1.34 and b = ln - 10
