Answer:

x² +4x

Step-by-step explanation:

Area of triangle= ½ ×base ×height

Given: base= 2x, height= x +4

Area of triangle

= ½(2x)(x +4)

= x(x +4)

= x(x) +x(4) <em>(</em><em>expand)</em>

= x² +4x

Answer:

Step-by-step explanation:

If a point (x, y) is translated by 4 units horizontally right and 1 unit upwards, coordinates of the image point will be,

(x, y) → (x + 4. y + 1)

Therefore, vertices of the image triangle ABC will be,

A(2, 2) → A'(2+4, 2+1)

           → A'(6, 3)

B(5, -1) → B'(5+4, -1+1)

           → B'(9, 0)

C(1, -2) → C'(1+4, -2+1)

           → C'(5, -1)

Then reflected across y-axis.

Rule for the reflection across y-axis will be,

(x, y) → (-x, y)

A'(6, 3) → A"(-6, 3)

B'(9, 0) → B"(-9, 0)

C'(5, -1) → C"(-5, -1)

Hello.

The answer is <em>D. It is reviewed and amended.  </em>The reason why is because the State Constitution(s) are usually longer than the regular Constitution, which has roughly 4,000 words. State Constitutions are normally 8,500 words or longer. So it takes a long time to amend because they are longer.

Sarah runs at a rate of 8 miles per hour what is her speed at feet per second
LekaFEV [45]

Answer:

i worked some of it out

Step-by-step explanation:

1 mile = 5,280ft

1 hour = 8 miles

30 min = 4 miles

15min = 2 miles

7.5 (7min and 30 sec) = 1 mile

3.75(225 sec) =1/2 mile = 2,640ft

0.25(quarter of a mile) = 1,320ft

i just completely lost myself but if this helps then great! sorry if i wasted your time
