Solve the formula a=1/2 bh for h. a. h=2ab b. h=a2b c. h=2ab d. h=2a−b

see explanation

Step-by-step explanation:

Given A = bh

multiply both sides by 2 to eliminate the fraction

bh = 2A ( divide both sides by b )

h =

That is, none of the listed options. Unless you omitted the division in C

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

i think the correct option is the second option.
