Answer 1

Answer:

Answer:

13) x=n-11

15) x=3*10

Step-by-step explanation:

I used x as the variable. The questions are pretty straightforward. They are asking you to put the terms in the description on the right side of the equation. The questions = x. That was probably confusing, but it is correct. I hope this helped!

Answer 2

Answer:

Product of 3 and 10 and12

Cut the sign in half across its middle. Then you have two right triangles.
They're congruent, so pick one to work with, and discard the other one
temporarily.

In the right triangle:

-- The length of one leg is 'x'.
-- The length of the other leg is (2x + 7).
-- The length of the hypotenuse is 35.47 inches.

You know that in any right triangle:

(The square of the hypotenuse) =
(the square of one leg) + (the square of the other one.)

so you can use that to find the value of 'x'.

One you know the value of 'x', go back to the whole sign before you cut it
in half, and notice that the height of the sign is '2x' ... which is the answer.

height =2x so we must find x then multiply by 2

if we cut the triangle in half from with the line from left to right, we have a trianlgle that is x high and 2x+7 wide and the hyposonuse that is 35.47 so
a^2+b^2=c^2
x^2+(2x+7)^2=35.47^2
x^2+4x^2+28x+49=1258.12
group like terms
5x^2+28x+49=1258.12
subtract 1258.12 from both sides
5x^2+28x-1209.12=0
factor 5(x-13.0008)(x+18.6008)=0
therefore
(x-13.0008) or/and (x+18.6008)=0
x-13.0008=0
add 13.0008 to both sides
x=13.0008

x+18.6008=0
subtract 18.6008 from both sides
x=-18.6008
since heights cannot be negative, this solution can be discarded

so x=13.0008
2x=height=26.0016

What are the values of the coefficients and constant term of 0 = 4 – 7x2 + x in standard form?a =
b =
c =

Answers

By definition, the standard parabola equation is given by:
$ax ^ 2 + bx + c = 0$
We then have the following quadratic equation:
$0 = 4 - 7x ^ 2 + x$
By rewriting the equation in its standard form, we have:
$- 7x ^ 2 + x + 4 = 0$
Comparing with the definition, we have that the values of the coefficients are given by:
$a = -7 b = 1 c = 4$
Answer:
The values of a, b and c are given by:
$a = -7 b = 1 c = 4$

Answer

a = -7 × 10⁰

b = 1 × 10⁰

c = 4 × 10⁰

Explanation

The general formula is; ax² + bx + c.

Where a ⇒ co-efficient of x²

b ⇒ co-efficient of x

c ⇒ The constant term

0 = 4 – 7x² + x This equation can be written in the form of ax² + bx + c.

0 = 4 – 7x² + x = -7x² + x + 4 = 0

Comparing the values of a, b and c in the equation in standard form are;

a = -7 × 10⁰

b = 1 × 10⁰ and

c = 4 × 10⁰

Edie can paint a wall in 3 hours. Dan can paint the same wall in 6 hours. if they work together, how many hours will it take Edie and Dan to paint the wall?A.
1 hour

B.
1.5 hours

C.
2 hours

D.
4.5 hours

Answers

Eddie can paint 1/3 in an hour
Dan can paint 1/6 wall in an hour

2/6 + 1/6 = 1/2
Together, they can paint 1/2 wall in an hour

1/2 x 2 = 2
Therefore they would paint the whole wall in 2 hours, so the answer's C.
