Answer:

b = 3.1

Step-by-step explanation:

Since the length of one of the longer sides, a, has been given to be 6.3, plug it into the equation.

2(6.3) + b = 15.7

12.6 + b = 15.7

b = 15.7 - 12.6

What is the value for y?<br><br><br><br> Enter your answer in the box.<br><br> y =
MArishka [77]

The given triangle has two sides marked equal and hence is an isosceles triangle.In isosceles triangle base angles are equal <A=<B=50.

Sum of angles in any triangle is 180 degrees.

<A+<B+<C=180°

50+50+5y+10=180

Adding like terms :

110+5y=180

Subtracting 110 on both sides:

5y=70

Dividing both sides by 5:

y=14.

Which second-degree polynomial function f(x) has a lead coefficient of 4 and roots 5 and 2? f(x) = 4x² +7x+10 f(x)=4x²+28x+40 O
makkiz [27]

The second-degree polynomial function f(x) that has a lead coefficient of 4 and roots 5 and 2 is f(x) = 4x² -28x + 40. The correct option is the last option f(x)=4x²-28x+40​

<h3>Quadratic equation</h3>

From the question, we are to determine which second-degree polynomial function f(x) has a lead coefficient of 4 and roots 5 and 2

To determine this, we will use the given roots to determine the equation

The roots are 5 and 2

Thus

x = 5 and x = 2

x - 5 = 0 and x - 2 = 0

Therefore,

(x -5)(x -2) = 0

Distributing

x(x -2) -5(x -2)  = 0

x² -2x -5x + 10 = 0

x² -7x + 10 = 0

Now, multiplying through by 4, we get

4x² -28x + 40 = 0

Thus, the function becomes f(x) = 4x² -28x + 40

Hence, the second-degree polynomial function f(x) that has a lead coefficient of 4 and roots 5 and 2 is f(x) = 4x² -28x + 40. The correct option is the last option f(x)=4x²-28x+40​
