Answer:

7x² - 6x + 4

Step-by-step explanation:

(4x² - x + 6) - (-3x² + 5x + 2)

4x² - x + 6 + 3x² - 5x - 2

4x² + 3x² - x - 5x + 6 - 2

7x² - 6x + 4

(-5,-1), m=-5/4 I'm using that as a fraction

inessss [21]

Point slope form
y-y1=m(x-x1)
m=slope
(x1,y1) is a point

(-5,-1)
x1=-5
y1=-1
m=-5/4

y+1=-5/4(x+5)
y=-5/4x-29/4

Please answer the question!

Airida [17]

ANSWER

$Area = 2\sqrt{3} \: {cm}^{2}$

EXPLANATION

We need to use the Pythagoras Theorem to find the height of the triangle.

${a}^{2} + {b}^{2} = {c}^{2}$

$({2 \sqrt{3}) }^{2} + {b}^{2} = {4}^{2}$

$12 + {b}^{2} = 16$

${b}^{2} = 16 - 12$

${b}^{2} = 4$

Take positive square root to get;

$b = \sqrt{4} = 2$

Area =½bh

$Area = \frac{1}{2} \times 2\sqrt{3} \times 2$

$Area = 2\sqrt{3} \: {cm}^{2}$

Find m>X <br> 21.04<br> 22.62<br> 67.38<br> 68.96

valina [46]

Answer:

67.38 degrees

Step-by-step explanation:

Here, we want to find the value of the angle at X

We are going to use the appropriate trigonometric ratio here

From the question, the vertex X faces the side 12 and that makes the side the opposite

The side 13 faces the right angle and that makes it the hypotenuse

The trigonometric ratio that connects both is the sine

so we have that;

sine X = 12/13

X = arc sin (12/13)

X = 67.38
