Answer:

f ( - 3 ) = 18

Step-by-step explanation:

f ( x ) = 2x²

Find f ( - 3)

let , x = - 3

lf ( - 3 ) = 2 ( -3 )²

f ( - 3 ) = 2 × ( - 3 )²

Evaluate the power

f ( -3) = 2 × 9

multiply the numbers

f ( - 3 ) = 18

1. Seven multiplied by three
7*3 the little star mean times

2. Twice the opposite of eleven= 2x+11
22 less than 3 times the number
3x-22
3x-22=2x+11
3x-2x=11+22
x= 33
So , it would be 2x+11 x is 33

Hope this helps good luck

Igoryamba

Answer:

70

Step-by-step explanation:

We know that to find the area of a triangle, you need is formula:

(base*height)/2

The height is 10 m and the base is 14 m, so the area is:

(10 m*14 m)/2

=140 m/2

=70 m

The area of the triangle is 70 m.

Please help me i'd really appreciate any help
garik1379 [7]

Congruent means they are the same length.

Set both lines equal to each other and solve for x:

x + 5 = 2x -10

Subtract x from both sides:

5 = x -10

Add 10 to both sides:

x = 15

Now you have a value for x, replace x in the equation of the line and solve:

QR = x +5 = 15 +5 = 20
