Answer:

Step-by-step explanation:

x2 - 12x+ 35 = x^2 - 7x -5x +35

                   = x ( x-7) - 5(x - 7)

                   = (x-7)(x-5)

<u>ANSWER:  </u>

The factors of the expression x^{2}-12x+35 are (x – 7) and (x – 5).

<u>SOLUTION: </u>

Given, Trinomial expression is x^{2}-12x+35

Trinomial is nothing but an expression or equation having three terms in it.  

Given expression is quadratic expression.

Now, to factorize any quadratic expression we need to write the constant term as product of two numbers, such that sum two number should equal to coefficient of x, in order to take common.

x^{2}-12 x+35

By writing constant as product of two numbers, we get

x^{2}-12 x+5 \times 7

By writing the “x” term as sum of two number coefficients, we get

x^{2}-7 x-5 x+5 \times 7

By taking x and  -5 as common

x(x – 7) –5(x – 7)

By taking (x – 7) as common, the above expression becomes,  

(x – 7)(x – 5)  

Thus factors of the expression X^{2}-12 X+35 are (x – 7) and (x – 5).

F(x) = x5 + (x + 3)2 x=-1
sveticcg [70]
Hello!

You put -1 in for x

F(-1) = (-1)^5 + (-1 + 3)^2

F(-1) = -1 + (2)^2

F(-1) = -1 + 4

F(-1) = 3

The answer is 3

Hope this helps!

Answer:

<em>x = y = 64° , z = 20°</em>

Step-by-step explanation:

<em>x = y</em> = \frac{180-52}{2} <em>= 64 </em>°

m∠ADC = 52° + x

m∠ADC = 52° + 64° = 116°

<em>z</em> = 180° - 116° - 44° <em>= 20</em> °

X+2a=12+ax-6a; a= Simplify
lara31 [8.8K]

Answer:

x+2a=12+ax-6a

Step-by-step explanation:

collect liked terms:

x+2a=12+ax-6a

2a-ax+6a=12-x

factorize a on the left hand side:

a(2-x+6)=12-x

divide both sides by (2-x+6) :

a(2-x+6)/(2-x+6)= 12-x/(2-x+6)

a= 12-x

____

(2-x+6)

Which sequence matches the recursive formula? an=2an-1+5, where a1=5. A) 5,10,15,20 B) 5,15,35,75. C)5,15,25,35. D) 5,20,35,40
Dominik [7]

The recursive formula

a_n = 2a_{n-1}+5

means that, to compute the next value, you have to double the previous one and then add 5.

So, we start with 5. To get the second term, we double it and add five, so we have

a_2 = 2\cdot 5+5 = 10+5 = 15

Next, we will double 15 and add 5:

a_3 = 2\cdot 15 + 5 = 30+5 = 35

So, the answer is B, because it's the only option starting with 5,15,35.

Just to check, let's compute the last step:

a_4 = 2\cdot 35 + 5 = 70+5 = 75

Which confirms option B
