Answer:

A. (7n-1) (8n-1)

Step-by-step explanation:

56n^2 -8n-7n+1

56n^2 -8n -7n+1

Factor out 8n from the first group and -1 from the second group

8n (7n-1) -1(7n-1)

Factor out the (7n-1)

(7n-1) (8n-1)

Answer:

A.) JH = 1 in

B.) GH = 3/4 in

C.) m∠F = 62°

D.) m∠J = 118°

Step-by-step explanation:

In a parallelogram, opposite angles are congruent, adjacent angles are supplementary, and opposite sides are congruent.

A.) JH = FG = 1 in

B.) GH = FJ = 3/4 in

C.) m∠F = m∠H = 62°

D.) m∠J = m∠G = 180° -62° = 118°

What is the vertex of the graph of the function f(x) = x2 + 8x - 2?

vlabodo [156]

Answer:

Vertex is (-4, -18)

Step-by-step explanation:

f(x) = $ax^{2} +bx +c$

Let (h, k) be the vertex

An easy way to find h is to use the formula h = -b/2a

In your case where f(x) = $x^{2} +8x - 2$ a = 2 and b = 8

So, h = -8/2(1) = -8/2 = -4

Substitue -4 in for x to find k

k = ( $-4^{2}$ ) + 8(-4) - 2

= (16) - 32 - 2

= 16 - 32 - 2

= -18

Vertex is (-4, -18)

Note: Another way to find the vertex is to complete the square, but this can really be difficult in some cases
