Step-by-step explanation:

Area of 5 = {(4x+3)×(2x+3-x-2)}+{(x+2)×(x+1)}

={(4x+3)×(x+1)}+{(x+2)×(x+1)}

Area of 6 = {(3x+8)×(3x+5-x-3)}+{(x+3)×(x+3)}

= {(3x+8)×(2x+2)}+{(x+3)×(x+3)

Hope u got it

The sum of three consecutive even integers is -78. What is the smallest integer? Show all working outs (5)

svet-max [94.6K]

Answer:

The smallest integer is -27 and the integers are -27, -26, and -25

Step-by-step explanation:

We can represent this with:

x + x - 1 + x - 2 = -78

Simplify.

3x - 3 = -78

Add 3 to both sides.

3x = -75

Divide both sides by 3.

x = -25

So, the first integer is -25.

Subtract two to get the smallest integer.

-25 - 2 = - 27

Mark is flying a kite and realizes that 300 feet of string is out. Mark anchored the kite to the ground. The angle of the string

Nadya [2.5K]

Answer:

The kite is 202.7 feet above the ground

Step-by-step explanation:

The scenario is depictedd in the picture attached

we have to find the height.

Trigonometric ratios will be used to find the height.

So,

$sin\ (42.5) = \frac{h}{300}\\ 0.6756=\frac{h}{300}\\0.6756*300=h\\202.68 = h$

The height is 202.68 feet

Rounding off to the nearest tenth

202.7 feet

Therefore, the kite is 202.7 feet above the ground ..
