8(x + 2) = 36.....distribute thru the parenthesis
8x + 16 = 36....subtract 16 from both sides
8x = 36 - 16
8x = 20...divide both sides by 8
x = 20/8
x = 5/2 or 2 1/2

Create a factorable polynomial with a GCF of 5z. Rewrite that polynomial in two other equivalent forms. Explain how each form wa

Mekhanik [1.2K]

Answer with explanation:

It is given that, G C F of two polynomials is 5 z.

We have to Write that two polynomials.

A=5 z² + 5 z =5× z× (z+1)

B=10 z + 5 z²=5×z×(z+2)

→→G C F ,of A and B=5 z

Now, writing polynomials in equivalent form

1.5 z² + 5 z =5× z× (z+1)=(z+1)×z×5=5 z + z²

2. 10 z + 5 z²=5×z×(z+2)=(z+2)×z×5=5 z² + 10 z

to write in equivalent form of above polynomials, we have used commutative property of addition ,and Multiplication ,which states that, A+B=B +A, and AB=BA.

And, Distributive property of multiplication with respect to addition and Subtraction.

1. A × (B +C)=A × B + A × C

2. A × (B -C)=A × B - A × C

Answer:

-24
>

Step-by-step explanation:

1. You can use a calculator if your knowledge of arithmetic fails you.

... 98 +17 +37 -176 = 152 -176 = -24

___

2. -37/8 = -(32 +5)/8 = -4 5/8 = -4.625

This number is on the left side of zero on the number line, but is slightly closer to zero than -4.63, so is "greater than" -4.63.

One leg of a right triangle is 28 inches longer than the other leg, and the hypotenuse is 52 inches. Find the lengths of the leg

katovenus [111]

Step-by-step explanation:

Let x represent the missing sides measurement.

x+x+28=52

combine like terms

2x + 28 = 52

subtract 28 from both sides

2x + 28 = 52

- 28 - 28

2x = 24

divide both sides by 2

x = 12

plug it back in

one leg is 12 inches

the other leg is 40 inches

Find all the missing elements:<br> B<br> 14<br> 15<br> 70°<br> A<br> b<br> с

photoshop1234 [79]

Answer:

$B=48.7\\$

$c=61.3$

$b=12$

Step-by-step explanation:

Using sines law for triangles,

$\frac{15}{sinA} =\frac{14}{sinc} =\frac{b}{sinB} \\\\A= 70$

⇒ $\frac{15}{sin70} =\frac{14}{sinC} =\frac{b}{sinB}$

⇒ $\frac{15}{0.9397} =\frac{14}{sinC}=\frac{b}{sinB}$

⇒ $15.9625=\frac{14}{sinC}$

⇒ $SinC=\frac{14}{15.9625}=0.8771$

⇒ $C=Sin^{-1}(0.8771)=61.29$

⇒ $C=61 ~ or ~ 61.30$

$\frac{b}{Sin B}=15.9625$

Now sum of angles a Δ is 180°

A+B+C=180°

$70+B+61=180$

$B=180-131=49~ or ~ 48.7$

$b=sin(48.70)(15.9625)=(0.7547)*(15.9625)= 12.0$
