How do you know if the equation for a problem is multiplication? Well, lets go and review: Multiplication is :<span>A </span>mathematical<span> operation performed on a pair of numbers in order to derive a third number called a product. For positive integers, </span>multiplication<span> consists of adding a number (the multiplicand) to itself a specified number of times. Thus </span>multiplying<span> 6. :)</span>
Step-by-step explanation:
18+ 5(2x + 5) = 12
18 + 10x + 25 = 12
43 + 10x = 12
10x = 12 -43
10x = -31
x = -3.1
Answer:
D. Infinitely many solutions
Step-by-step explanation:
The equation simplifies to ...
2h -16 -h = h -16
h -16 = h -16 . . . . . . a "tautology", true for all values of h.
There are infinitely many solutions.
X^2+4x+4+12x+24-14=0
x^2+16x+14=0
x= -16 ± √(16)^2-4(1)(14) /2(1)
=-16± √200 /2
-16 ± 2√50 /2
-16 ± 10√2 /2
-8 ± 5√2
