it is 87 inches since there are 12 inches in a foot and there are 7. Multiply 7 and 12 to get 84 then add 3 = 87
The solution is the number that 'x' must be in order to
make the equation a true statement.
5 + 2x = 2x + 6
Subtract 2x from each side: 5 = 6
<em>No</em> value for 'x' can make 5 equal to 6 .
So the equation has no solution.
The common ratio is 2:1, or dividing by 2

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
subtraction:
5/8 - 1/8 = 4/8which reduces to 1/2 pound left
