First use the distributive property, then combine like terms.
6 + 7 (8b + 4) = 6 + 7(8b) + 7(4)
= 6 + 56b + 28
= (6 + 28) + 56b
= 34 + 56b

Answer:

£30

Step-by-step explanation:

From the question, we know that:

Ed buys vase for £24 and adds 25% onto the price before putting it into his shop window.

Step 1

We find the amount added onto the price.

This is calculated as:

£24 × 25%

£24 × 25/100

= £6

Step 2

what does the price tag say in the window?

The amount that the price tag says is calculated as:

£24 + £6

= £30

The amount that the price tag says is £30

1. The function f(x) = –0.05(x2 – 26x – 120) represents the path coming out of the cannon. If x is the horizontal distance from

LenaWriter [7]

Question 1

f(x) represents the distance of the cannon from the ground

Question 2

When f(x) = 0, there will two values of 'x'. The point on the positive x-axis where the graph crosses represent the point where the cannon hits the ground.

Question 3

Yes, it would. By knowing the spot where the cannon will hit the ground, we can set the net at the spot.

Question 4

f(x) = 0
-0.05 (x² - 26x -120) = 0
x² - 26x - 120 = 0

Question 5

Please refer to the table attached below

Question 6

The value of p and q that gives the correct factors are -30 and 4 since it gives p+q = -26

Question 7

Factorising the equation completely

-0.05 (x² - 26x - 120) = 0
-0.05 (x+4) (x-30) = 0
(x+4) (x-30) = 0

Question 8

Solving the equation

x+4 = 0 and x-30=0
x=-4 and x=30

Question 9

The roots of the equation is x = -4 and x = 30

Question 10

Please refer to the third graph

Question 11

Yes

Question 12

The negative zero means the initial distance of the cannon, where it was fired from

Question 13

The distance between x = -4 and x = 30 is 34 units. If the cannon was fired from the point when x = -4, the cannon will hit the ground again 34 units from the point it was fired from. If Nik put a net 30 units from the firing point, the cannon will fly pass it.
