Plug in the two expressions
270 = (7x + 6) + (6x - 7) -> expand
270 = 42x^2 - 1 -> bring the one to the other side and add
271 = 42x^2 -> divide by 42
6.4 = x^2 -> find the square root
2.5 = x
Then solve both equations with x = 2.5 :^)
Hope this helped!!

Answer:
okay mate
Step-by-step explanation:
2 *7/8
2 gets cancelled and it is 7/4
2 Is the greatest common factor, therefore you’d cancel out the 8 by dividing it by 2. since 2/2=1 you can leave it and 8/2=4 therefore your answer is 7/4. hope this helped your confidence !

A line passes through the given points. Write an equation for the line in point-slope form. Then rewrite the equation in slope-intercept form. (1 , 1/2), (3, 2)
A) y + 1/2 = 3/4 ( x + 1 ) ; y = 3/4x + 1/4
B) y − 1/2 = 3 ( x − 1 ) ; y = 3x − 1/4
C) y − 1/2 = 3/4 ( x − 1 ) ; y = 3/4x − 1/4

Assuming that the pots are arranged in a straight line, each pot would have a diameter of 5, because 5 • 3 = 15, and 15 is the length of the box. The radius of the base of one pot is therefore 2.5.

Erik used the Factor Theorem to find the remainder of 2x3-4x2-28x+6 divided by x+3. If he calculated the remainder to be 0, what does that tell him?
Answers
Step-by-step explanation:
x + 3 = 0
x = - 3
f(x) = 2x³ - 4x² - 28x + 6
f(- 3) = 2(- 3)³ - 4(- 3)² - 28 x (- 3) + 6
= 2 x (- 27) - (4 x 9) + 84 + 6
= - 54 - 36 + 90
= - 90 + 90
= 0
Therefore,
x + 3 is factor of 2x³ - 4x² - 28x + 6
