Answer:

There are no statements supplied, but see below.

Step-by-step explanation:

This is a perfect square trinomial (quadratic) because it factors to

(2x + 5)^2.

The zeroes are -5/2 multiplicity 2.

It is a parabola which opens upwards and whose vertex touches the x axis at the point (-5/2, 0).

I need help pls What is angle 3

N76 [4]

Answer:

Step-by-step explanation:

4x + 6 + 3x + 21 = 8x + 7

7x + 27 = 8x + 7

-x + 27 = 7

-x = -20

x = 20

m<3= 8(20) + 7

160 + 7 = 167

m<1= 4(20) + 6 = 80 + 6 = 86

m<2= 3(20) + 21 = 60 + 21 = 81

How do you solve 6x + 2(x-4)=8+4(x+2)

babunello [35]

Answer:

$\LARGE{ \underline{\underline{ \sf{\pink{ Required\: answer:}}}}}$

6x + 2 ( x - 4) = 8 + 4 ( x + 2)

6x + 2x - 8 = 8 + 4x + 8

Arranging like terms 

6x + 2x - 4x = 8 +8 - 8

8x - 4x = 8

4x = 8

x = 8/4

x = 2
