-10(1 - 9x) + 6(x - 10) Pics pls

Galina-37 [17]

Answer:

$\boxed{\sf{96x-70}}}$

Step-by-step explanation:

Use the distributive property.

<h3>What is a distributive property?</h3>

Distributive property is a serving to distribute or allot or disperse.

Distributive property:

A(B+C)=AB+AC

A(B-C)=AB-AC

-10(1-9x)+6(x-10)

Expand.

-10(1-9x)

-10*1=-10

-10*9x=90x

$\longrightarrow \sf{=-10+90x+6\left(x-10\right)}}$

6(x-10)

6*x=6x

6*10=60

6x-60

Rewrite the problem down.

= -10+90x+6x-60

Combine like terms.

90x+6x-10-60

Add the numbers from left to right.

90x+6x=96x

96x-10-60

Finally, subtract the numbers from left to right.

-10-60=-70

$\Longrightarrow \boxed{\sf{96x-70}}$

Therefore, the final answer is 96x-70.

I hope this helps, let me know if you have any questions.

A contractor needs to put a carpet in the hallway of a house, the diagram of the houses is below.All of the sides of the figure

Vera_Pavlovna [14]

Break it into squared and rectangles and find the area of those first then add it all together

For your square you would get 16 ft squared

For your rectangle you would get 32 ft squared

For your other rectangle you would get 32 ft squared as well

Then add those all together to get the full answer

80 ft squared

Hope this helps :)

The function, f(x) = –2x2 + x + 5, is in standard form. The quadratic equation is 0 = –2x2 + x + 5, where a = –2, b = 1, and c =

avanturin [10]

Given:

The function, f(x) = -2x^2 + x + 5

Quadratic equation: 0 = -2x^2 + x +5
where a = -2
b = 1
c = 5

The discriminate b^2 - 4ac = 41

To solve for the zeros of the quadratic function, use this formula:

x = ( -b +-√ (b^2 - 4ac) ) / 2a

x = ( 1 + √41 ) / 4 or 1.85
x = ( 1 - √41 ) / 4 or -1.35

Therefore, the zeros of the quadratic equation are 1.85 and -1.35.
