X -(2x- 3x-4/7) = 4x -27/3 -3

RUDIKE [14]

RHS
=4x-27/0
=not defined=0

LHS
=x-2x+3x+4/7=2x+4/7=(14x+4)/7= 14x+4.

14x=-4

x=-4/14

X=-2/7

Hi there, hope everyone is well and staying cool :D

Answer:

A) By using the Pythagorean Theorem, we will see that $8^2 + 15^2 = 17^2$ . If we simplify it, we will find that the hypotenuse of Δ $ABC = 17$

B) approximately $18.79$

Step-by-step explanation:

A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!

***Pythagorean Theorem is $leg^2 + leg^2 = hypotenuse^2$

B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, $8^2 + 17^2 = AD$ .

$8^2 + 17^2 = 64 +289$

$64 + 289 = 385$

$\sqrt{385} \\$ ≈ $18.79$

Hope you do well on the rest of your math problems :D
