Answer:

8b is 220

Step-by-step explanation:

it might be 220 because we already know that from o to b is 140 degrees. We know that a full circle is 360, so take 140 away from 360, and you get 220.

360-140=220 degrees

Im not sure about the other questions but i hope this helps :)

If h(x) = x - 7 and g(x) = x^2, which expression is equivalent to (gºh) (5)?

gulaghasi [49]

Answer: a) (5 - 7)²

Step-by-step explanation:

g(x) = x^2 h(x) = x - 7

h(5) = 5 - 7

g(h(5)) = g(5 - 7) = (5 - 7)² Replace the x in g(x) with (5 - 7)

5x+8=9x+12 helpppppp

Marina CMI [18]

Hi there! :)

Answer:

$\boxed{X=-1}$

*THE ANSWER MUST HAVE A NEGATIVE SIGN!*

Step-by-step explanation:

First, you subtract by 8 from both sides of an equation.

5x+8-8=9x+12-8

Subtract.

12-8=4

5x=9x+4

Then, you subtract by 9x from both sides of an equation.

5x-9x=9x+4-9x

Simplify by equation.

-4x=-4

Divide by -4 from both sides of an equation.

-4x/-4=-4/-4

Divide by the numbers from left/right.

-4/-4=-1

$\boxed{X=-1}$ , is the FINAL/CORRECT ANSWER! :)

Have a nice day! :)

Please help me ive never done one like this

inessss [21]

Given:

DE = (6x - 9) cm

EF = (4x + 4) cm

LM = 14 cm

MN = 16 cm

To find:

The value of x.

Solution:

If three or more parallel lines intersect two transversals, then they cut off the transversals proportionally.

$$\Rightarrow \frac{DE}{EF} =\frac{LM}{MN}$

$$\Rightarrow \frac{6x-9}{4x+4} =\frac{14}{16}$

Do cross multiplication.

$$\Rightarrow 16( {6x-9})=14 ({4x+4} )$

$$\Rightarrow 96x-144=56 x+56$

Add 144 on both sides.

$$\Rightarrow 96x-144+144=56 x+56+144$

$$\Rightarrow 96x=56 x+200$

Subtract 56x from both sides.

$$\Rightarrow 96x-56x=56 x+200-56x$

$$\Rightarrow 40x=200$

Divide by 40 on both sides, we get

$$\Rightarrow x=5$

The value of x is 5.
