Is anyone good at geometry if so can someone help me please ?

NO LINKS PLEASE

B.) 9 cm
Explanation: thats shape is a trapezoid
The formula for the area of a trapezoid is:
Base + Base divided by 2 x height

If we follow that formula, in this case it will be:
4.9 + 9.9/2 x h = 66.6
4.9 + 9.9 = 14.8
14.8/2 = 7.4

Now, we need to find the missing height.

We will divide the area (66.6 cm2) by 7.4

66.6/7.4 = 9

The missing height is 9cm2.

MARK BRAINLIEST PLS
if you have any questions, com ment me.

X=3 and y=4 is the answer

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
