If x=2 calculate the value of x squared +2x

Mathematics
1 answer:
Mazyrski [523]3 years ago
5 0
Firstly, I substituted the x for 2 in the equation 2^2+2(2). 
Secondly, simplify 2(2) to 4 so 2^2+4
Thirdly, simplify 2^2​​ to 4 so 4+4.Fourth, 4+4 is 8.

Recall that the sum of the measures of the angles of a triangle is 180°. In the triangle below, angle Chas the same measure as a
Effectus [21]

The measure of each angles a,b and c are 32°, 74°  and 74°  respectively.

What is triangle?
Three edges and three vertices define a triangle as a polygon. One of geometry's fundamental shapes is this one. The symbol for an ΔABC triangle is A, B, and C.
Any three points determine a distinct triangle and a distinct plane in Euclidean geometry when they are non-collinear (i.e. a two-dimensional Euclidean space). To put it another way, each triangle is contained in a plane, and there is only one plane that includes that particular triangle. All triangles are contained in one plane if and only if all geometry is the Euclidean plane, however this is no longer true in higher-dimensional Euclidean spaces. Except as otherwise specified, the subject of this article is triangles in Euclidean geometry, more specifically, the Euclidean plane.

Let angle b be x

Therefore angle c will also be  x [as given b and c are equal] and angle a will be x - 42°.
Now as we know that the sum of the measures of the angles of a triangle is 180° therefore,

x + x + x - 42° = 180°

=> 3x = 222°

=> x = 74°  which is angle b and c

and angle a is (74 - 42)°  =32°

An airplane travels about 1,500 Km in a straight line between Toronto and Winnipeg. However, the plane must climb to 10,000 m du
Anna007 [38]

Answer:416

Step-by-step explanation: Based on the given problem above, it requires a trigonometric solution. So here it goes:

The climb distance is:200 * Sec [ArcTan [10/200]] = 10√ 401 km

and the decent distance is:300 * Sec [ArcTan [10/300]] = 10√901 km

So add the given results above with 500 km and this will be the additional distance that plane moves through the air.

The answer would be in the unit meters.

((10√401 +10√901−500)∗1000)=416 meters

Hope this is the answer that you are looking for.

What is the slope of (-3,-6) and (4,7)​
Gelneren [198K]

Answer:

13/7

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(7-(-6))/(4-(-3))

m=(7+6)/(4+3)

m=13/7

Find 5/7 ÷ 3 and how did you find it
Zarrin [17]

Answer:

5/21

Step-by-step explanation:

1. 5/7 divided by 3 is the same as 5/7 divided by 3/1

2. when dividing a fraction, multiply by the reciprocal, so it would be 5/7 times 1/3

3. multiply the numerator and denominators, so 5x1 and 3x7

4. the answer is 5/21

hope this helped!
