I can't see pictures, but I'll try.

To find area, you multiply the two dimensions. To find a dimension with the area and a dimension, you divide the area by the dimension provided.

(2x+10)(2x+15)

x=2

2(2)+10x2(2)+15

4+10x4+15

14x19

I’m confused on this one
Mandarinka [93]

Remark

If the lines are parallel then triangle RQS will be similar to triangle RTP


From that, all three lines in one triangle will bear the same ratio to all three lines of the second triangle.


Givens

PQ = 8

QR = 5

RS = 15

ST = x + 3


Ratio

QR/RP = RS/RT


Sub and solve

RP = 5 + 8

RP = 13


RT = 15 + x + 3

RT = 18 + x


5/13 = 15 / (18 + x) Cross multiply

5(18 + x) = 195 Remove the brackets on the left.

90 + 5x = 195 Subtract 90 from both sides.

5x = 105 Divide by 5

x = 105/5

x = 21 Answer <<<<<<<

A cost of a pair of football boots have been decreased from £70 to £52.50, what was the percentage change?
alisha [4.7K]
I think it’s 25%


Because 70 divided by 10 is 7
Which is then 10% so 20% is 14 then 5% is half of 7 which is 3.5
So 70 -7-7-3.5=52.5 which is 25%

Scilla [17]
To answer this we just need to set up a equation:- 

895 - 669 - 100 = 126.

SO, after these transactions you will have $126 left. 

Hope I helped ya!!
