On a scale drawing, the height of a tree is 3.75 inches. if the scale of the drawing is 1 in: 50ft, how tall is the tree?

187.5

Step-by-step explanation:

50 × 3 =150

50 ÷ 4 = 12.5

12.5 ×3= 37.5

150 + 37.5 =187.5

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
