Answer:

m = 24

Step-by-step explanation:

m + 7° + 2m + 11° = 90°

3m + 18° = 90°

3m = 90°- 18°

3m = 72

(divide both sides by 3)

therefore : m = 24

Answer: A & C

Step-by-step explanation:

$i=\sqrt{-1}$

$\sqrt{-1} *\sqrt{4} =\sqrt{-4}$

You can also simplify the above by taking the -4 out of the radical

It becomes 2 x $\sqrt{-1}$ , which can be simplifed to C

How do you factor 7b^2-63b+140?

LuckyWell [14K]

You can simplify the entire equation by dividing it all by 7, resulting in 7(b^2-6b+20).

Here, you can factor as you normally would. Your X values would have to be found using the quadratic formula.

PLEASE HELP ME PLS ITS MATH

Ganezh [65]

Answer:

Step-by-step explanation:

We know that

$h(t)=-16t^2+1296$

The balls hits the ground when h(t)=0, so

$-16t^2 + 1296=0 \\ \\ t^2 - 81=0 \\ \\ t^2 = 81 \\ \\ t=9$

Note I only considered the positive case because time must be positive.
