$\\ \sf\longmapsto 1+tan^2A$

$\boxed{\sf tanA=\dfrac{sinA}{cosA}}$

$\\ \sf\longmapsto 1+\dfrac{sin^2A}{cos^2A}$

$\\ \sf\longmapsto \dfrac{cos^2A+sin^2A}{cos^2A}$

$\boxed{\sf cos^2A+sin^2A=1}$

$\\ \sf\longmapsto \dfrac{1}{cos^2A}$

$\\ \sf\longmapsto \dfrac{1}{1-sin^2A}$

$\\ \sf\longmapsto \dfrac{1}{1}-\dfrac{1}{sin^2A}$

$\\ \sf\longmapsto \dfrac{1}{sin^2A}$

Hence verified

One number is the square of another. their sum is 182. find the numbers.

wariber [46]

$n-first\ number\\n^2-second\ number\\\\\text{The equation:}\\\\n+n^2=182\qquad\text{subtract 182 from both sides}\\\\n^2+n-182=0\\\\n^2+14n-13n-182=0\\\\n(n+14)-13(n+14)=0\\\\(n+14)(n-13)=0\iff n+14=0\ \vee\ n-13=0\\\\\boxed{n=-14\ or\ n=13}\\\\n^2=(-14)^2=196\ ot\ n^2=13^2=169\\\\Answer:\ \boxed{196\ and\ -14\ or\ 169\ and\ 13}$

Use algebra to solve the following question 7x + 3 = -11

meriva

Answer:

x = -2

Step-by-step explanation:

7x + 3 = -11

-3 -3 subtract both sides by 3

7x = - 14

7x/7 = - 14/7 divide both sides by 7

-14/7 = -2
