Answer:

(2x+5)(4x+3)

Step-by-step explanation:

Given the expression 8x^2 + 26x + 15

Factorize

8x^2 + 26x + 15

= 8x^2 + 6x + 20x + 15

= 2x(4x+3) + 5 (4x+3)

= (2x+5)(4x+3)

Hence the factored form of the expression is (2x+5)(4x+3)

Can anyone help me on that question too its math plsss

Assoli18 [71]

Answer:

2x= 40°

5x= 100°

Step-by-step explanation:

2x on opposite angle because it is an isosceles triangle

2x+ 2x+ 5x = 180° (angles of a triangle)

9x= 180

x= 180/9

x= 20°

Sub

2(20)= 40°

5(20)= 100°

What is the rang y=-x2 - 2x + 3?

Damm [24]

This is a downward facing parabola, so its range comes in the form

$(-\infty, m)$ where m is the y coordinate of the vertex of the parabola.

We can find the x coordinate of the vertex using

$x=-\dfrac{b}{2a}=-\dfrac{-2}{-2}=-1$

And if we plug -1 in the equation we get the y coordinate of the vertex:

$y=-(-1)^2-2(-1)+3 = -1+2+3=4$

So, the range is the interval

$(-\infty, 4)$
