The side of the triangle is 13 inches
Side of square. 6 inches
X= side of square
4x+15 =3(x+7)
4x+15=3x+21
x=6
6+7= 13
Perím square 6x4= 24
Perim triangle 13x3=39
39-24=15
Step-by-step explanation:
0.2x² − 0.8x = 1.6
Multiply both sides by 5.
x² − 4x = 8
Complete the square by adding 4 to both sides.
x² − 4x + 4 = 12
(x − 2)² = 12
x − 2 = ±√12
x = 2 ± √12
The positive solution is x = 2 + √12 ≈ 5.46.
Time = 1,419/65 = about 21,8h
about 109 gallons of gas
the trip cost = $394,58 i guess
Answer:
486m^4
If this ^ means exponents.
Answer:
2x^2+5
Step-by-step explanation:
2x times x is 2x squared
add 4 and 1
so it would 5
so 2x sqaured plus 5
