Answer: 4x² + 3x + 52

Step-by-step explanation:

1. rearrange & simplify terms:

(4x² - 4 + 6) + (3x - 7² + 1) . . .

(4x² + 2) + (3x + 49 + 1) . . .

(4x²+2) + (3x + 50).

2. combine like terms in standard form:

What is (-m)⁻³n if m = 2 and n = -24?

Galina-37 [17]

Answer:

-3

Step-by-step explanation:

(-2)^-3 x (-24)

(-2)^3 becomes 1/(-2)^3 in order to make the negative exponent a positive one.

then, you do 1/-8 (the -8 is the (-2)^3 simplified) x -24

1/-8 x (24) = 24/-8 = -3.

Hope this helps! :)

Vertex A in quadrilateral ABCD lies at (-3, 2). If you rotate ABCD 180° clockwise about the origin, what will be the coordinates

natali 33 [55]

The rule for a rotation by 180° about the origin is (x,y) -->(−x,−y)

So A(-3, 2) to A'(3, -2)

Answer:

57°

noname [10]

Answer:

c = 29

Step-by-step explanation:

Law of sines is given as: $\frac{a}{sin(A)} = \frac{b}{sin(B)} = \frac{c}{sin(C)}$

B = 180 - (57 + 44) = 79°

b = 41

C = 44°

c = ?

Thus:

$\frac{b}{sin(B)} = \frac{c}{sin(C)}$

Substitute

$\frac{41}{sin(79)} = \frac{c}{sin(44)}$

Multiply both sides by sin 44

$\frac{41}{sin(79)}*sin(44) = \frac{c}{sin(44)}*sin(44)$

$\frac{41*sin(44)}{sin(79)}*sin(44) = c$

c = 29.0140633 ≈ 29

A basket contained 75 brown eggs. 40% of them were used-up, and a third of them remaining were rotten and thrown out. What fract

IceJOKER [234]

Answer:

4/15

Step-by-step explanation:

40% is the same as .4.

.4 x 75 = 30

1/3 x 75 = 25

30 + 25 = 55

75 - 55 = 20

20 / 75

Simplify. Divide by 5.
