7x² + 6x - 1<br> Algebra 3|factoring
GaryK [48]

Answer:

(7 x - 1) (x + 1)

Step-by-step explanation:

Factor the following:

7 x^2 + 6 x - 1

Factor the quadratic 7 x^2 + 6 x - 1. The coefficient of x^2 is 7 and the constant term is -1. The product of 7 and -1 is -7. The factors of -7 which sum to 6 are -1 and 7. So 7 x^2 + 6 x - 1 = 7 x^2 + 7 x - x - 1 = (7 x - 1) + x (7 x - 1):

(7 x - 1) + x (7 x - 1)

Factor 7 x - 1 from (7 x - 1) + x (7 x - 1):

Answer: (7 x - 1) (x + 1)

The perimeter of a rectangle can be found using the equation P = 2L + 2W, where P is the perimeter, L is the length, and
a_sh-v [17]

Answer:

No, that is not possible

Explanation:

P = 2L + 2W

Insert numbers into equation

p=(2)(20)+(2)(11)

Step 1: Simplify both sides of the equation.

p=(2)(20)+(2)(11)

p=40+22

p=(40+22)(Combine Like Terms)

p=62

p=62

The perimeter is 62, not 64, so the perimeter can't be 64 if the length 20 and the width is 11.

Find the volume of the cylinder. Round your answer to the nearest tenth.
Ipatiy [6.2K]

Step-by-step explanation:

r = 6 \: in \\ h = 7 \: in

Volume Of Cylinder

= \pi \: r {}^{2} h

=  \frac{22}{7}  \times 6 \times 6 \times 7 \\  \\  = 22 \times 36 \\  = 11 \times 2 \times 36 \\  = 11 \times 72 \\  = 792

thus the volume of cylinder is 790 cubic inches (nearest tenth)
