0=7x+14-4
0=7x+12
7x=-12
x=-12/7
Answer:
12. 6.4
13. 20
Step-by-step explanation:
This is the Pythagorean theorem, which says a^2+b^2=c^2. So for problem 12 we have 4^2+5^2=c^2. Since, 16+25=41, c=sqrt41 which is about 6.4. For problem 13 we have 15^2+b^2=25^2. Since 25^2-15^2=400, b=sqrt400 which is 20. Hope this helps!
Answer:
x = -10, x=5
Step-by-step explanation:
x^2 +5x - 50 = 0
What two number multiply to -50 and add to 5
10 * -5 = -50
10 + -5 = 5
( x+10) (x-5) =0
Using the zero product property
x+10 =0 x-5 =0
x+10-10 =0-10 x-5+5=0+5
x= -10 x =5
Applying the tangent ratio, the distance from A to C across the gorge, is: 60.6 ft.
<h3>What is Tangent Ratio?</h3>
The tangent ratio for solving a right triangle is given as, tan ∅ = opposite/adjacent.
Given the following:
- ∅ = 25°
- Adjacent length = 130 ft
- Opposite length = AC
Apply the tangent ratio:
tan 25 = AC/130
AC = (130)(tan 25)
AC = 60.6 ft
