Find the area of the following
triangle:
5.7 cm
4 cm
13 cm
A= [?] cm

26 cm

Step-by-step explanation:

To find the area of a triangle, you must use the formula A=1/2xbxh.

For this triangle, the base is 13 and the height is 4. So, multiply the 13 by 4 to get a total of 52, and then divide by 2 to get your final answer of 26.

the amount you'd have after the work is $1.55

step-by-step explanation:

you subtract 95% from $31.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
