Answer:

x = -4

Step-by-step explanation:

First, the pharenthesis: 8x-3 = 5*2x+5*1

8x -3 =10x+5

then take all the Number with x to the left, the ones without to the right, by changing their sign.

8x -10x = 5 +3

-2x = 8

now divide by -2

-2x/-2=8/-2

x=-4

What is the area of this triangle 12 m 13 m and 5 m is the measurements of the triangle

VashaNatasha [74]

Answer:

30 m^2.

Step-by-step explanation:

This is a right-angled triangle because it obeys the Pythagoras theorem

( 13^2 = 12^2 + 5^2).

So its area = 1/2 * base * height

= 1/2 * 5 * 12

= 30 m^2

Multiply the following rational expressions and simplify the result

GarryVolchara [31]

Answer:

Step-by-step explanation:

We have to solve the given expression,

$\frac{9y-33y^2-3y^4}{100-49y^2}.\frac{7y^2+17y+10}{14y^2+28y}$

$\frac{9y-33y^2-3y^4}{100-49y^2}.\frac{7y^2+17y+10}{14y^2+28y}$ = $\frac{-y(-9+33y+3y^3)}{100-49y^2}.\frac{7y^2+17y+10}{14y(y+2)}$

= $\frac{-y(-9+33y+3y^3)}{(10-7y)(10+7y)}.\frac{7y^2+10y+7y+10}{14y(y+2)}$

= $\frac{-y(-9+33y+3y^3)}{(10-7y)(10+7y)}.\frac{y(7y+10)+1(7y+10)}{14y(y+2)}$

= $\frac{-y(-9+33y+3y^3)}{(10-7y)(10+7y)}.\frac{(y+1)(7y+10)}{14y(y+2)}$

= $\frac{-3y(-3+11y+y^3)}{(10-7y)}.\frac{(y+1)}{14y(y+2)}$

= $\frac{-3(-3+11y+y^3)}{(10-7y)}.\frac{(y+1)}{14(y+2)}$

= $\frac{3(3-11y-y^3)(y+1)}{(10-7y)(14(y+2)}$

Anybody know how to do # 14, 15, and 16? Would also be nice if yall told me if any of these were wrong

mote1985 [20]

Step-by-step explanation:

1. Right

2. Right

3. Right

4. Right

5. Right

6. Right

7. Its not properly visible sorry for this.

8. Its wrong

$(\frac{1}{3} ) {}^{2} = \frac{1}{9}$

9. Right

10. Its wrong

$0.5 {}^{3} = 0.125$

11. Right

12. Its wrong.... Bcz square of minus is plus

$- 9 {}^{2} = 81$

13. Right

14. According to the BODMAS rule..

$15 - 7 \times 2 + {2}^{3}$

$15 - 14 + 8$

$1 + 8 = 9$

15.

$(11 - 8) {}^{2} - 2 \times 6$

$3 {}^{2} - 12$

$9 - 12 = - 3$

16.

$12 + \frac{ {9}^{2} }{3}$

$12 + \frac{81}{3}$

$12 + 27 = 39$
