Answer:

92

Step-by-step explanation:

These triangles are similar because they share a common angle and two pairs of sides in the same ratio.

Sides of the bigger triangle are double of those of the smaller triangle

46+46 = 92

A right isosceles triangle has an area of 65cm^2. What's the length of each leg to the nearest tenth of a cm.
Andreas93 [3]

Well, we know that the legs of this triangle are equal, and we know
that the area of any triangle is  (1/2)(base)(height) .

Since this is a right triangle, we can set it down on one leg, and then
the other leg will be the height.  Then ...

    Area = (1/2) (base) (height)

             = (1/2) (leg) (leg)

    65 cm²  =  (1/2) (leg)²

Multiply each side by  2 :  130 cm²  =  (leg)²

Take the square root of each side:      leg = √130 cm²  =  11.402 cm

                                        rounded to the nearest tenth:    11.4 cm

Q,If one of the zeroes of the cubic polynomial x3 + px² + qx + r is -1, then the product of the other two zeroes is​
Yuki888 [10]

Answer:

q- p + 1

Step-by-step explanation:

Let p(x) = x³ + px² + qx + r  

p(-1) = 0

(-1)³+p(-1)²+q(-1) + r = 0

-1+ p -q + r = 0

r = q- p + 1

The triangles are similar what is the value of x
givi [52]
The triangle is 4 times bigger so multiply 25 by 4 that will give you 100 =6x + 28

subtract 28 from both sides then divide 6 by the answer you get after subtracting.


x = 12

6 times 12 equals 72. 72 plus 28 equals 100.

What is the equation of the graphed linear model? y = x + <br><br> Graph:
Tomtit [17]
One point on the line is (1,3) and another point is (9,11).

Find the slope of the two points on the line.

\bf{Slope =\frac{y_2-y_1}{x_2-x_1} =\frac{11-3}{9-1} =\frac{8}{8} = 1

Now, let's make our equation in the form of y = mx + b, where m is the slope and b is the y-intercept.

We now have y = 1x + b

Plug in a point and solve for b.

y = 1x + b

3 = 1(1) + b

3 = 1 + b

b = 2


The equation is y = x + 2.
