Answer:

x = 49

Step-by-step explanation:

Since the line is parallel, the value of 2x - 8 is equal to 90.

=> 2x - 8 = 90

=> 2x = 98

=> x = 49

Answer:

x = 49

Step-by-step explanation:

2x - 8 and the right angle are corresponding angles and are congruent , then

2x - 8 = 90 ( add 8 to both sides )

2x = 98 ( divide both sides by 2 )

x = 49

Henry packed some apples in a box. The total mass of the box and the apples was 16 240 g. He packed some strawberries in a simil

icang [17]

Step-by-step explanation:

x = mass of apples

y = mass of strawberries

z = mass of the box

x = 3y

x + z = 16240

y + z = 6350

let's subtract the second from the first equation

x + z = 16240

- y + z = 6350

-----------------------

x - y + 0 = 9890

using the first identity in that result gives us

3y - y = 9890

2y = 9890

y = 4,945 g

x = 3y = 3×4945 = 14,835 g = the mass of the apples

Which binomial is a factor of 9x^2-64

larisa86 [58]

This is an example of a factor pattern called the Difference of Two Squares.

$A^2-B^2=(A+B)(A-B)$

What is playing the role of A? What do you square to get $9x^2$ ? That would be $3x$ .

What is playing the role of B? What do you square to get 64? That would be 8.

Your expression factors as $(3x+8)(3x-8)$
