Answer:

f(-4) = 72, f(x + 5) = 3x² + 23x + 36

Step-by-step explanation:

f(-4) = 3(-4)² - 7(-4) - 4

= 48 - (-28) - 4

f(-4) = 72

f(x + 5) = 3(x + 5)² - 7(x + 5) - 4

= 3(x + 5)(x + 5) - 7(x + 5) - 4

= 3(x² + 10x + 25) - 7(x + 5) - 4

= 3x² + 30x + 75 - 7x - 35 - 4

f(x + 5) = 3x² + 23x + 36

Can someone please HELP me on how to do this

frutty [35]

Answer:

4)x= g-c

5)x =u+k

6)x = g-c

7) $a=\frac{k}{u}$

8) $x= \frac{g}{c}$

9) $a=\frac{4}{12m}$

10) $x= \frac{2c+3}{3}$

11) $a=\frac{n+p}{m}$

12) $a= \frac{ub}{k}$

13)a= d -r + c

14) $x=\frac{np}{m}$

Step-by-step explanation:

4) g= c+x

x= g-c

5) u=x-k

x =u+k

6)g = c+x

x = g-c

7) $u=\frac{k}{a} \\\\a=\frac{k}{u}$

8) g=xc

$x= \frac{g}{c}$

9) 12am = 4

$a=\frac{4}{12m}$

10)-3x+2c = -3

2c = -3 +3x

2c +3 = 3x

$x= \frac{2c+3}{3}$

11) am= n+p

$a=\frac{n+p}{m}$

12) $u = \frac{ak}{b} \\\\u*b = ak\\\\a= \frac{ub}{k}$

13)a-c = d-r

a= d -r + c

14)xm= np

$x=\frac{np}{m}$

Need help on question 4??

Anit [1.1K]

HK consists of two part, HJ and JK

HK = HJ + JK

We know that:

HK = 12.2ft

JK = 3.1ft

HJ = ?

Let's plug our values into the equation above.

12.2ft = HJ + 3.1ft

Subtract 3.1ft from both sides.

9.1ft = HJ
