Answer:

Area: 40 cm²

Perimeter: 24 cm

Step-by-step explanation:

Area of Triangle

To find the area of a triangle, you need to do 1/2bh.

b*h = 80. Divide by 2, you get 40 cm²

Perimeter of Triangle

Just add up all the sides! 10 + 8 + 6 = 24 cm!

Please help What is x= ?

Nataly [62]

Answer:

$x=33^{\circ}$

Step-by-step explanation:

First off, your drawing is kinda inaccurate, because the $124^{\circ}$ looks like a right angle, but as you drew it yourself it doesn't matter too much.

We know that the sum of the angles of a triangle will always equal $180^{\circ}$ , so we have that $23+124+x=180$ .

Combining like terms on the left side gives $147+x=180$ .

Subtracting $147$ from both sides gives $x=33$ .

So, $\boxed{x=33^{\circ}}$ and we're done!

If the distance traveled is (4s3 - 6s² + 4s + 14) miles and the rate is (s + 1) mph, write an expression, in hours, for the time

BartSMP [9]

The equation for time is URM:

$time = \frac{distance}{speed \: (rate)}$

$t(s) = \frac{4s {}^{3} - 6s {}^{2} + 4s + 14}{s + 1} = \frac{2(s + 1)(2s {}^{2} - 5s + 7) }{s + 1} \\ t(s) = 2(2s {}^{2} - 5s + 7) \\ t(s) = 4s {}^{2} - 10s + 14$
