PLEASE LOOK at the photo and help me on these 2 questions :(!!!!!

Tems11 [23]

Answer:

1) f(g(2)) = 24

2) f(g(-1)) = -4

Step-by-step explanation:

1) GIven f(x) = x²+2x and g(x) = 2x

f(g(x)) = f(2x)

f(2x) = (2x)² + 2(2x)

f(2x) = 4x² + 4x

f(g(x)) = 4x² + 4x

f(g(2)) = 4(2)² + 4(2)

f(g(2)) = 16+8

f(g(2)) = 24

2) f(x) = x+1 and g(x) = 5x

f(g(x)) = f(5x)

f(5x)= 5x + 1

f(g(x)) = 5x + 1

f(g(-1)) = 5(-1) + 1

f(g(-1)) = -5+1

f(g(-1)) = -4

Multiply (2x+3) (-x -2)

Marysya12 [62]

Answer:

$-2x^{2} -7x-6$

Step-by-step explanation:

(2x + 3) (-x - 2)

distribute first term, to the second term:

2x(-x) + 2x(-2) + 3(-x) + 3(-2)

multiply:

$(-2x^{2})$ + (-4x) + (-3x) + (-6)

$-2x^{2} -4x-3x-6$

combine the like terms:

$-2x^{2}$ - 4x - 3x - 6

-7x

$-2x^{2}$ - 7x - 6

final answer :

$-2x^{2}$ - 7x - 6

hope this helped !!

mark me brainliest :D

Which equation can be used to solve for m∠1? m∠1 = One-half(a – b) m∠1 = One-half(a + b) m∠1 = One-half(c – d) m∠1 = One-half(c

Artemon [7]

Answer:

$m\angle 1=\frac{1}{2}(arc\ a+arc\ b)$

Step-by-step explanation:

The picture of the question in the attached figure

we know that

The measure of the<u><em> interior angle</em></u> is the semi-sum of the arches that comprise it and its opposite.

so

$m\angle 1=\frac{1}{2}(arc\ a+arc\ b)$

The figure below represents a play space that Logan fenced in for his dog.

Wittaler [7]

Answer:

Difference in area = 75 ft²

Step-by-step explanation:

Case 1 (When logan had only one dog):

length of the play space= $12$ ft

breadth of the play space= $10$ ft

we know that area of a rectangle is length times breadth (length x breadth)

therefore, area of the play space= $12*10$

= $120ft^{2}$

Case 2(When Logan had two dogs):

Given: Logan wants to increase the length of the play space by 3 feet and width by 3 feet

⇒length of the play space= $12+3$ ft= $15$ ft

breadth of the play space= $10+3$ ft= $13$ ft

we know that area of a rectangle is length times breadth (length x breadth)

therefore, area of the play space= $15*13$

= $195ft^{2}$

Therefore difference in the area of play space = $195-120$

=75 ft²
