Answer: The correct option is (C) 7.

Step-by-step explanation: We are given to find the value of 'c' in the following quadratic equation:

$3x^2+5x+7=0~~~~~~~~~~~~~~~~~~~~~~(i)$

We know that

the standard quadratic equation is of the following form:

$ax^2+bx+c=0,~a\neq 0.$

So, a is the coefficient of x², b is the coefficient of x and c is the constant term in the equation.

Comparing equation (i) with the standard quadratic equation, we get

the constant term, c = 7.

Thus, the required value of c is 7.

Option (C) is CORRECT.

Rewrite 8^(9/5) as a radical expression. I think it might be D, I'm unsure though.

AnnZ [28]

It is D, Nancy Reynolds from Chicago.

The denominator of the exponent is the index of the radical, the base of the exponent is the base of the radical, and the numerator of the exponent is the exponent of the radicand.

$8^{\frac{9}{5}}= \sqrt[5]{8^9}$

Zoey solved the calculation 5 + 3.89 using a decimal number line. The decimal number line shows how Zoey calculated the answer.

IceJOKER [234]

Start at the point 0
Then move 5 points right because 5 is positive
The another 3.89 points right because your adding a positive number
Sooo 5 + 3.89 = 8.89

Hope this helps :D

The ratio of the perimeters of two similar triangles is 4:7. What is the area of each of these triangles if the sum of their are

arsen [322]

Answer:

16 cm^2 and 49 cm^2

Step-by-step explanation:

The ratio of areas is the square of the ratio of linear dimensions, so is ...

(4/7)^2 = 16/49

The sum of these "ratio units" is 16 +49 = 65. The sum of triangle areas is 65 cm^2, so each "ratio unit" must stand for 1 cm^2 of area. That is, the triangles must have areas of ...

16 cm^2
49 cm^2
