Write the missing factor.

Mathematics
1 answer:
SSSSS [86.1K]4 years ago
7 0

Answer:

Answer is option B. (8+7x)

Step-by-step explanation:

In these questions we always simplify the equation to get the value of missing factor.

We assume that the missing factor is y.

The given equation is (64-49x^{2})=(y)(8-7x)

8^{2}-(7x)^{2} =(y)(8-7x)

(8-7x)(8+7x) = (y)(8-7x)

y = \frac{(8-7x)(8+7x)}{(8-7x)}

y = (8+7x)

What is the solution to the equation? 7x + 6 = -22
trapecia [35]

C.) x = -4 is the correct answer

Step-by-step explanation:

In order to solve the equation we have to isolate x on one side of equation

Given

7x + 6 = -22

Subtracting 6 from both sides

7x+6-6=-22-6\\7x=-28

Dividing both sides by 7

\frac{7x}{7}=\frac{-28}{7}\\x=-4

Hence,

C.) x = -4 is the correct answer

Answer:

The length side of the original square banner was 9 ft

Step-by-step explanation:

Let

x-----> the length side of the original square banner

we know that

The new area of the banner is equal to

91=(x+4)(x-2)

Solve for x

91=(x+4)(x-2)\\ \\91=x^{2}-2x+4x-8\\ \\x^{2}+2x-99=0

Solve the quadratic equation by graphing

The solution is x=9 ft

see the attached figure
