For what values of x will the function f(x) = 7x ^ 2 + 27x - 4 equal zero?

Mice21 [21]

Answer:

The function f(x) will equal zero when x = 2/17.

Step-by-step explanation:

Combine like terms and set the resulting expression equal to zero. We get:

f(x) = 34x - 2 = 0

Adding 2 to each 34x - 2 and 0, we get 34x = 2. Solving this for x yields

x = 2/17

The function f(x) will equal zero when x = 2/17.

The tiles show a factorization of 4x^2+6x+2. Write the factorization shown by the tiles.

stellarik [79]

Answer:

2(x + 1)(2x + 1)

Step-by-step explanation:

$y = 2(2x^2 + 3x + 1)$

Factor the trinomial in parentheses.

Since a - b + c = 0, use shortcut. One real root is -1 and the factor is (x + 1). The other root is: $\frac{-c}{a}= -1/2$

and the factor is $(x+\frac{1}{2})$

Factor form of y:

y = 2(x + 1)(2x + 1)

A rectangular garden is enclosed by 94 feet of fencing around its perimeter. The garden is 15 feet wide. How long is the garden?

scZoUnD [109]

94-30=60
30 because there are four sides to a rectangle and two of them are 15 feet (wide) so 15+15=30
