Plz HELP! WILL GIVE BRAINLIEST! 1. Consider the picture below. Find the measure of ∠CEA.

pashok25 [27]

Answer:

103°

Step-by-step explanation:

The marked angles have the same measure, so ...

14x+7 = 12x +17

2x = 10 . . . . . subtract 12x+7

x = 5 . . . . . . . divide by 2

(14x +7)° = 77°

∠CEA is supplementary to the marked angles:

∠CEA = 180° -77°

∠CEA = 103°

What is the smallest multiple of 18 of the form 2A945B, where A and B are digits?

musickatia [10]

Answer:

$219456$

Step-by-step explanation:

It must end in $0,2,4,6,8$ (divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).

The digit sum is $2+A+9+4+5+B=20+A+B$ .

We want to make $A$ as low as possible because it's a higher digit than $B$ .

If $A$ is as low as possible, we have that the sum is $20+0+7=27$ . Uh-oh. $B$ has to be even! So $A=0$ doesn't work.

If $A=1$ , we have that the sum is $20+1+6=27$ . Yay!

So, the answer is $\boxed{219456}$

Answer:

7. Ans;

$\frac{6 {a}^{5} {b}^{7} }{ - 2 {a}^{3} {b}^{7} } = \frac{2 {a}^{3} {b}^{7}(3 {a}^{2} ) }{ - 2 {a}^{3} {b}^{7} } = - 3 {a}^{2}$

___o____o___

8. Ans;

$\frac{ - 20 {x}^{3} {y}^{2} }{ - 5 {x}^{3}y } = \frac{ - 5 {x}^{3}y(4y) }{ - 5 {x}^{3}y } = 4y$

___o___o___

9. Ans;

$\frac{ - 16 a {b}^{4} }{4 {b}^{3} } = \frac{4 {b}^{3}( - 4ab) }{4 {b}^{3} } = - 4ab$

____o____o____

10. Ans;

$\frac{21 {m}^{8} {n}^{5} }{27 {m}^{5} {n}^{4} } = \frac{3 {m}^{5} {n}^{4}(7 {m}^{3} n) }{3 {m}^{5} {n}^{4}(9) } = \frac{7 {m}^{3}n }{9}$

___o___o___

11. Ans;

$\frac{ - 15 {x}^{5} {y}^{4} }{45x {y}^{3} } = \frac{ 15x {y}^{3} ( - {x}^{4} y)}{15x {y}^{3}(3) } = - \frac{ {x}^{4}y }{3}$

___o___o___

12.Ans;

$\frac{7 {p}^{2} {q}^{2} }{14 {p}^{2} {q}^{2} } = \frac{7 {p}^{2} {q}^{2} }{7 {p}^{2} {q}^{2} (2) } = \frac{1}{2} = 0.5$

Solve!!!!! PLEASE HELP!!! MKE BRAINLIEST! 2x^2 - 28 = x^2 + 15 What is the answer!

padilas [110]

Answer:

x = ± sqrt(43)

Step-by-step explanation:

2x^2 - 28 = x^2 + 15

Subtract x^2 from each side

2x^2-x^2 - 28 = x^2-x^2 + 15

x^2 -28 = 15

Add 28 to each side

x^2 - 28 +28= 15+28

x^2 = 43

Take the square root of each side

sqrt(x^2) = ± sqrt(43)

x = ± sqrt(43)
