What are the values of c makes x^2 + 6x + c a perfect square trinomial? 3
6
9
12

Answers

As per the given data, he value of c that makes x^2 + 6x + c a perfect square trinomial is c = 9.

What is trinomial?

A trinomial is a polynomial composed of three terms or monomials in elementary algebra.

To determine the value of c that makes x^2 + 6x + c a perfect square trinomial, we need to use the formula:

(a + b)^2 = a^2 + 2ab + b^2

In this case, we want to find two numbers a and b such that:

x^2 + 6x + c = (x + a)^2

Expanding the right-hand side, we get:

(x + a)^2 = x^2 + 2ax + a^2

Comparing the two expressions, we see that:

The linear coefficient of x is 2a

The constant term is a^2

Therefore, we need to find a number a such that 2a = 6 and a^2 = c. Solving for a, we get a = 3, and substituting into a^2 = c, we get c = 9.

Therefore, the value of c that makes x^2 + 6x + c a perfect square trinomial is c = 9.

Answer:

c = 9

Step-by-step explanation:

(a+b)^2=a^2+2ab+b^2\n\n\text{We have}\ x^2+6x+c=x^2+2(x)(3)+c\n\n\text{Therefore}\ c=3^2=9\n\nx^2+2(x)(3)+3^2=(x+3)^2

Lynne bought a bag of grapefruit, 1 and 5/8 pounds of apples, and 2 and 3/16 pounds of bananas. The total weight of her purchases was 7 and 1/2 pounds. How much did the bag of grapefruit weigh?

Answers

The answer would be 3 and 11/16.
First add the 1 and 5/8 to 2 and 3/16.
Subtract this sum from the total 7 1/2 pounds. This will give the weight of grapefruit.
Let, the weight of Grapefruit = x
It would be: x + 1 5/8 + 2 3/16 = 7 1/2
x + 13/8 + 35/16 = 15/2
16x+26+35 /16 = 15/2
16x+61/16 = 15/2
2(16x+61) = 15*16
32x + 122 = 240
x = 118/32
x = 3.68 
x = 3 11/18 Pound

In short, Your Answer would be 3 11/18 Pound

Hope this helps!
