Answer:
x=-3/11
Step-by-step explanation:
(x+3)/5 +2x=0
Multiply both sides by 5 to get rid of the fraction
5*( x+3)/5 +5*2x=0*5
x+3 + 10x =0
Combine like terms
11x +3 = 0
Subtract 3 from both sides
11x+3-3 =0-3
11x = -3
Divide by 11
11x/11 = -3/11
x = -3/11

Answer:
4. height: 5√3 cm; area: 25√3 cm²
5. 30√2 ft ≈ 42.43 ft
Step-by-step explanation:
4. The height of an equilateral triangle is (√3)/2 times the side length, so is ...
height = (√3)/2 × (10 cm) = 5√3 cm
The area is given by the formula ...
A = 1/2bh
A = 1/2(10 cm)(5√3 cm) = 25√3 cm²
__
5. The diagonal of a square is √2 times the side length, so the distance from 3rd to 1st base is ...
(30 ft)√2 ≈ 42.43 ft
__
The length of the diagonal of a square is something you should be familiar with. If you're not, you can figure the distance using the Pythagorean theorem.
d = √(30² +30²) = √1800 ≈ 42.43 . . . feet
Answer:
25 percent
Step-by-step explanation:
Of means multiply and is means equals
P * 56 = 14
Divide each side by 56
P = 14/56
P = .25
To change to a percent, multiply by 100
P = 25 percent
