The area of a square with sides of 2 feet is 4 square feet. The area of a square with sides of 4 feet is 16 square feet. what equation fits this data?Choices

y=4x
or
y=x+2
or
y=x squared
or
y=2x

Answers

Answer 1

Answer: A square, by definition, is an equilateral quadrilateral. It has already been established that the formula for the area of a square is to take the square of the length of its one side. To prove this,

A = 2^2 = 4
A = 4^2 = 16

Thus, the equation is y = x squared

Solve for d.5d+2(2-d)=3(1+d)+1
a)no solution
b)d=4
c)infinitely many solutions
d)d=-3

Answers

5d + 2(2 - d) = 3(1 + d) + 1
5d + 2(2) - 2(d) = 3(1) + 3(d) + 1
5d + 4 - 2d = 3 + 3d + 1
5d - 2d + 4 = 3d + 3 + 1
3d + 4 = 3d + 4
-3d    -3d
   4 = 4
   d = 0

$5d+2(2-d)=3(1+d)+1 \n 5d+4-2d=3+3d+1 \n 3d+4=3d+4 \n 0=0 \n \boxed{C.\ Infinitely\ many\ solutions}$

11. Quadrilateral GHJK is similar toquadrilateral RSTU. If GH = JK = 10,
HJ = KG = 14, and RS = TU = 16, what is
the scale factor of quadrilateral GHJK to
quadrilateral RSTU?

Answers

Answer: the scale factor is 1.6

Step-by-step explanation:

The attached photo shows Quadrilateral GHJK and Quadrilateral RSTU. Since they are similar quadrilaterals,

KG/UR = JG/TS = GH/RS = KJ/UT

10/16 = 14/TS

10TS = 16×14 = 224

TS = UR = 224/10 = 22.4

The scale factor is

16/10 = 22.4/12 = 1.6

Answer:

115

Step-by-step explanation:

Answer:

x = 115°

Step-by-step explanation:

We know that a triangle has 180° in total when you add up all the interior angles. So in order to find the value of x°, we need to find the missing angle in the triangle itself:

180°-(75°+40°)

= 180° - 115°

= 65°

To find x°, we know that the 65° angle + x° is equal to 180° because it's a supplementary angle. So:

x° + 65° = 180°

x° = 115°

Second gardener: 20min / 5 bushes = 4min/bush

Third gardener: 48 min / 8 bushes = 6min/bush

Milli plans to rent a room for her birthday party for $40. The catering charge is $12 per person but there is no charge for Milli's meal since she is the guest of honor. If Milli has $100 to spend on her birthday party, how many guests can she invite?

Answers

Since Milli has $100 to spend on her birthday party and she will pay $40 so the remaining money left for her party is $60. For the $60 left she will then pay $12 for each guest for catering. Divide $60 by $12, the answer is 5. Therefore Milli will have 5 guests for her birthday.
