Answer:

Side length: z + 4

Perimeter: 64

Step-by-step explanation:

Hello!

Since the area of a square is the square of the sde length,

using the special binomial product formula: (a+b)² = a² + 2ab + b²:

  • z² + 8z + 16
  • (z + 4)²

The side length of the square is (z+4)².

The perimeter is 4(z + 4), where z is 12:

  • 4(12 + 4)
  • 4(16)
  • 64

The side length is z + 4, the perimeter is 64

Josie took a road trip. She drove for 45 minutes at 70 miles per hour. Then she drove 15 minutes at 20 miles per hour. How far d
Hunter-Best [27]

Answer:

Therefore Josie drove  57.5 miles.

Step-by-step explanation:

Speed: The ratio of distance to time.

To find the distance we use the following formula

Distance= time \times speed

Given that Josie drove 45 minutes at 70 miles per hour.

45 \ minutes= \frac{45}{60}\ h=\frac34\ h

In 45 minutes, she traveled  = (70\times \frac34) \ miles

                                                =52.5 miles.

The she drove 15 minutes at 20 mile per hour.

15 \ minutes= \frac{15}{60}\ h=\frac14\ h

In 15 minutes, she traveled =(20\times \frac 14) \ miles

                                            =5 miles

Therefore Josie drove (52.5+5) miles= 57.5 miles.

This purse is roughly a trapezoid. The bottom base is 16 inches long. The top base is 10. It stands 13 inches tall. The latch is
balandron [24]
To find the amount of fabric for one side of the purse you will find the area of the trapezoidal space that is created.  The latch is on the top, so the 2 in is not necessary information.

A = 1/2 h(b1 + b2)
      1/2 x 13 x (10 + 16)
A = 169 square inches of fabric will be needed.

Please help I’m really confused. I will give BRAINLIEST!
stiv31 [10]

Answer:

t = 115

s = 60

g(x) = 10/23x - 10

Step-by-step explanation:

find s first since its easy (it goes up by 10's)

then take a pair from the table that corresponds such as 69 for x and 30 for g(x) and turn them into a fraction:

69/30

do the same for t:

t/50

equal 69/30 to t/50 and solve using cross multiplication:

69/30 = t/50 =  

30t = 3450

/30      /30

t = 115

honestly had a little hard time finding the equation but basically I simplified the fraction 30/69 to get 10/23 for slope and then I insert a corresponding x and y value into y= mx+b with the slope value to find b.
