You would need to facto 2x² + 9x - 35 to get (2x - 5)(x + 7).

We can find this first by dividing the 2x² into 2x and x, which we can put into the brackets:

(2x _ _)(x _ _)

Then we need to find two factors of -35 that have a difference of 9 when one is multiplied by 2, which gives us +7 and -5 as (7 × 2) - 5 = 14 - 5 = 9.

This gives our final answer as:

(2x - 5)(x + 7)

We cannot use foil on this expression as there are no brackets to expand.

I hope this helps!

The formula for the area of a triangle is, 1 А A= bh Calculate the height of a triangle when A= 24 m2 and b = 8 m.

Sphinxa [80]

I hope this helps you

A=1/2.b.h

given Area is 24 and base is 8

24=1/2.8.h

24=4.h (divide 4 both of sides)

h=6 (height)

Heron’s formula: Area = square root 5(5-a)(5-b)(5-c) What is the area of triangle DFG? Round to the nearest whole square unit. 2

timurjin [86]

To do this problem, you will need to know the side lengths of the triangle. If you have those, just plug them in for a, b, and c and evaluate the square root.

Here is an example. If the sides are 3, 4, 5.
It would be:

$A= \sqrt{6(6-3)(6-4)(6-5))}$

The 6 is in the formula because it is the semi-perimeter (half).

Find an exact value.<br><br> <img src="https://tex.z-dn.net/?f=cos%28-%20%5Cfrac%7B%20%5C77%20%5Cpi%20%20%20%20%7D%7B12%7D%29%20

$\cos\left(-\dfrac{7\pi}{12}\right)=\cos\dfrac{7\pi}{12}$

Recall that

$\cos^2x=\dfrac{1+\cos2x}2$

Let $x=\dfrac{7\pi}{12}$ , so that

$\cos^2\dfrac{7\pi}{12}=\dfrac{1+\cos\dfrac{7\pi}6}2=\dfrac{1-\dfrac{\sqrt3}2}2=\dfrac{2-\sqrt3}4$
$\cos\dfrac{7\pi}{12}=\pm\sqrt{\dfrac{2-\sqrt3}4}=\pm\dfrac{\sqrt{2-\sqrt3}}2$

Since the angle $\dfrac{7\pi}{12}$ lies in the second quadrant, you know that the cosine must be negative, so

$\cos\dfrac{7\pi}{12}=-\dfrac{\sqrt{2-\sqrt3}}2$

Two trains left Mooseport at the same time. One traveled north at 83 mph. The other traveled south at 67 mph. After how many hou

oee [108]

First of all, remember if 2 people are walking away from each other at the same speed (ex 4 mph), after 1 mile, they would be 8 miles away. 4 miles south and north. So these trains go away from each other at a total of 150 mph( 67 + 83). So your equation is h = hours, 150h = 600. Divide both sides by 150 to get h = 4. 4 hours is your answer.
