Answer:

your question is wrong, it's not an expression but a quadratic equation. if so your answer will be x=8±2√7

Step-by-step explanation:

by using, completing the square method

x²-16x-4=0

x²-16x=4

x²-16x+(-16×0.5)²=4+(16×0.5)²

x²-16x-8²=4+8²

(x-8)²=68

x-8=√68

x-8=±2√7

so x=8±2√7

Answers

Answer:

40cm²

Step-by-step explanation:

ΔABC ≅ ΔDEF

The length AB = 28 and the length of DE = 7. Since these are corresponding sides, we know that DEF= 1/4 (ΔABC)

So, since ΔABC = 160, we know that ΔDEF will be 1/4 of that, meaning that ΔDEF is 40.

ΔDEF = 40cm²

Answer:

10 cm2

Step-by-step explanation:

When two similar figures have a ratio of 4:1, the difference between their areas is:

[tex](4)^{2} :(1)^{2}[/tex]

That is, the dimension of the area of the largest figure is 16 times larger than the smallest figure.

So for this case:

the area of the larger figure is

ΔABC = 160 sq.cm

Then the area of the minor figure is:

ΔDEF= 160/16 = 10 sq.cm

486 in.2

Answers

The area of the enlarged picture on the wall is gotten as; D: 486 in²

How to use center of Dilation?

The formula for Linear scale factor is;

L.S = Image distance/object distance

Thus, from the attached image, we can find the Linear scale factor as;

L.S = OL'/OL

L.S = 54/ 12

L.S = 9/2

Area scale factor is equal to the square of linear scale factor. Thus;

Area scale factor = (9/2)²

Area scale factor = 81/4

Now,

81/4 = Area of larger rectangle/Area of smaller rectangle

Area of the smaller rectangle = 4 ×6 = 24 in²

Thus;

Area of enlarged picture on wall = (81/4) × 24

Area of enlarged picture on wall = 486 in²

Answers

Because we can't divide by zero, csc(θ) is undefined when θ = 0°, so the correct option is A.

For what value of θ is csc(θ) undefined?

First, remember that:

[tex]csc(\theta) = 1/sin(\theta)[/tex]

And also remember that we can't divide by zero.

Then the function csc(θ) is undefined for the values of θ such that sin(θ) = 0.

We know that sin(0°) = 0.

Then csc(0°) is undefined. This means that the correct option is the first one.

Answers

The equation in point slope form is y-1 = 1/4(x - 12)

Equation of a line

The formula for calculating the equation of a line is expressed as;

y = mx + b

m is the slope

b is the intercept

Slope = 1+3/12+4

Slope = 4/16

Slope = 1/4

For the intercept

1 = 1/4(12) + b

b = 1 - 3

b = -2

The standard form is:

4y - x = -8

How to get the standard form of the line?

We know that the point-slope equation of the line is:

y - 1 = (1/4)*(x - 12)

Expanding the right side, we get:

y - 1 = (1/4)*x - 3

Now we can move the term with x to the left side:

y - (1/4)*x = +1 - 3

y - (1/4)*x = -2

Now we can multiply both sides by 4:

4y - x = -8

This is the standard form of the linear equation.

After spending $60 at the electronics store, Jay earned 15 points. If Jay spends 40 at the store, how many points will he earn?

Answers

If Jay spends 40 at the store, the number of points he will earn is; 10 points

How to solve direct variation?

Let the number of rewards points a customer earns be y

Let the amount of money, in dollars, that the customer spends at the store be x.

Since the number of rewards points a customer earns varies directly with the amount of money, in dollars, that the customer spends at the store, then we can say that;

y ∝ x

Thus;

y = kx

where k is the constant of proportionality.

We are given x = 15 when y = $60. Thus;

60 = 15k

k = 60/15

k = 4

If Jay spends $40, it means the number of points will be;

The height for w = 3 is:
