a(8x + 7) = 4x + 3.5

8ax + 7a = 4x + 3.5

equating coefficients of x : 8a = 4  so a = 1/2

also 7a = 3.5 so a = 1/2

The value of a is 1/2

Answer:

792 m^2

Step-by-step explanation:

We can split the shape up into two different shapes. The first shape is the bigger rectangle, with an area of 18 x 30.  The second shape will have an area of 6 x (60-18). This is because we have to subtract the length of the large rectangle's side. The two areas are 540 and 252. When we add them together, we get 792. Since this is the area, it will be squared, leaving us with 792 m^2.

Hope this helps :)

Answer choices:
vova2212 [387]
A and T are points. On their own, they cannot define a line. So we can rule out choice A

WCR and TRA are angles. For any triple the points do not fall on the same straight line. So we cannot define any lines here. This crosses off choice B

Choice C is the answer because WC does define a line. We only need two points to form a line. Similarly CR does the same job. We draw a line marker with two arrows at each end to be placed over the letters to indicate "line". 

Choice D is similar to choice D; however, it is not the answer because WT is the same line as WC. In other words, WC = WT. We haven't named a new line at all. We're simply repeating ourselves.
