Step-by-step explanation:

Hey, there!!

Let's do it simply, ok.

Given that,

$= - 2 {x}^{2} + 8x + 10$

Take (-2) common to make it easy.

$= -2( 2 {x}^{2} - 8x - 10)$

= -2{ x^2-(5-1)x -5}

Multily with x,

= -2 {x^2-5x+x-5}

Taking common,

= -2{x(x-5) +1(x-5)

= -2{(x+1)(x-5)}...is your required answer.

Hope it helps...

Two right triangles are graphed on a coordinate plane. One triangle has a vertical side of 2 and a horizontal side of 6. The oth

Vikki [24]

Consider two right triangles:

1. ΔABC with vertices A(0,0), B(0,2), C(6,0). Then AB is perpendicular to AC and AB=2 units (vertical leg), AC=6 units (horizontal leg).

2. ΔXYZ with vertices X(6,-10), Y(6,0), Z(36,-10). Then XY is perpendicular to XZ and XY=10 units (vrrtical leg), XZ=30 units (horizontal leg).

The equation of the line BC is

$\dfrac{x-0}{6-0}=\dfrac{y-2}{0-2},\\ \\-x=3y-6,\\ \\x+3y-6=0.$

Check whether points Y and Z lie on this line:

Y(6,0): $6+3\cdot 0-6=0$ - true;

Z(36,-10): $36+3\cdot (-10)-6=0$ - true.

Answer: the hypotenuses of these two triangles could lie along the same line

Answer: note I will just replace the Shape by an X

a) X + 9 = 9 + 6; X=6 Commutative Propertie

b) 0 + X = 7; X=7 Additive Identity Propertie

c) X + (7 + 3) = (4 + 7) + 3; X=4 Associative Propertie

Step-by-step explanation:

There are four mathematical properties which involve addition. Commutative, associative, additive identity and distributive properties.

Commutative property: When two numbers are added, the sum is the same regardless of the order of the addends.

Associative Property: When three or more numbers are added, the sum is the same regardless of the grouping of the addends.

Additive Identity Property: The sum of any number and zero is the original number.

Distributive property: The sum of two numbers times a third number is equal to the sum of each addend times the third number.
