Answer:

12y + 5x - 15

Step-by-step explanation:

$7y + 4x - 10 + 5y - 5 + x$

$7y + 5y = (7 + 5)y = 12y$

$12y + 4x - 10 - 5 + x$

$4x + x = 4x + 1x = (4 + 1)x = 5x$

$12y + 5x - 10 - 5$

$- 10 - 5 = - (10 - 5) = - 15$

$= 12y + 5x - 15$

Simplify 15 to the 18th power over 15 to the 3rd power.

worty [1.4K]

The rule for quotients of similar bases with different exponents is:

(a^c)/(a^b)=a^(c-b) in this case:

15^18/(15^3)=15^15

PLEASE HELP ME RN PLEASE

Advocard [28]

Answer:

$\frac{n^{2} - 1 }{2}$

$\sqrt{29}$

Step-by-step explanation:

Area of triangle=1/2×b×h

$\frac{1}{2} \times (n - 1)(n + 1)$

$\frac{( {n}^{2} + n - n - 1) }{2 }$

$\frac{ {n}^{2} - 1 }{2}$

2. Area of triangle=14

$\frac{ {n}^{2} - 1 }{2} = 14$

${n}^{2} - 1 = 28$

${n}^{2} = 29$

$n = \sqrt{29}$
