Please help with this question will give brainliest.

Evgesh-ka [11]

Answer:

A=9in,b =9in

Step-by-step explanation:

This is a right angled triangle

Formula = a2×b2=c2 (ie sq of both adj sides equals the sq of the longest side)

So, a2 × b2 = c2

But both sides are equal, so we can as well say 2(a2) = (9|2)^2

2a^2 = 162

Divide through by 2

A^2 = 81

So, a = |81

A = 9

And since both sides are equal, a = b = 9

12x+7<-11 or 5x-8>40

DaniilM [7]

Answer:

Step-by-step explanation:

Given

12x + 7 < - 11 or 5x - 8 > 40

Solve each inequality

12x + 7 < - 11 ( subtract 7 from both sides )

12x < - 18 ( divide both sides by 12 )

x < - $\frac{3}{2}$

5x - 8 > 40 ( add 8 to both sides )

5x > 48 ( divide both sides by 5 )

x > $\frac{48}{5}$

Solution is

x < - $\frac{3}{2}$ or x > $\frac{48}{5}$ → A
