What’s the length of AZ. If A is between Y and Z, Y A = 22, AZ = 16x, and Y Z = 166

VLD [36.1K]

Answer:

c) 144

Step-by-step explanation:

Since A is between Y and Z,

$YZ = YA + AZ$

$116 = 22 + 16x\\16x = 116 - 22\\16x = 144\\x = 9$

however, the question asks for $the length of AZ$ , not the value of x.

Thus,

$AZ = 16x$

$AZ = 16\\$ × $9$

$AZ = 144$

D is the centroid of △ABC. What is the value of x when GD=x+4 and GC=4x+5?

alexira [117]

Answer:

x = 7

Step-by-step explanation:

Because:

GD = x + 4

GC = 4x + 5

And D is the centroid of ABC

So GC = 3GD

<=> 4x + 5 = 3(x + 4)

<=> 4x + 5 = 3x + 12

<=> 4x - 3x = -5 + 12

<=> x = 7

Done!!

You ok?? :))

Need Help Please, This One Is A Bit Difficult.

Answer: 432 units²

Step-by-step explanation:

The figure is composed by two trapezoids.

The formula for calculate the area of a trapezoid is:

$A=\frac{h}{2}(B+b)$

Where "B" is the larger base, "b" is the smaller base and "h" is the height.

Let be $A_f$ the area of the figure, $A_1$ the area of the trapezoid on the left and $A_2$ the area of the trapezoid of the right. Then the area of the figure will be:

$A_f=A_1+A_2$

$A_f=\frac{h_1}{2}(B_1+b_1)+\frac{h_2}{2}(B_2+b_2)$

Substituting values, you get:

$A_f=\frac{16units}{2}(25units+4units)+\frac{10units}{2}(25units+15units)=432units^2$

The area of a triangle is 150 cm^2. If the area of a triangle is given by the formula A=0/5b*h, write an equation which relates

taurus [48]

Answer:

Step-by-step explanation:

If the area of a triangle is 150cm^2, the formula would look like:

150=0.5b*h

So, if we were to solve for the base in terms of h, we'd simply divide both sides by 0.5b getting:

(150)/(0.5b)=h

which simplifies to

h=300b
