A= a+b over 2 times height
18 + 8 = 26
26 divide by 2 = 13
13 x 6 = 78
area is 78
0 in a tenths place and rounded the ones to 7. Rounded to the nearest 10th is 7
Hi,
From the picture you can see how 5x and 4x add up to 90°.
4x + 5x = 90°
9x = 90°
x = 10°
Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistake.
Answer:
Terms: 4x, -
Coefficients: 4, 
Step-by-step explanation:
The terms of an expression are the numbers and variables that are being added. In this expression 4x is being added to -. This means that they must be the terms. The coefficients are the constants that come before a variable. A variable is an unknown number represented by a letter, in this case, x. So the coefficients are 4 and because both these numbers are being multiplied by a variable.
5400*0.04(rate)=216
Because it's simple interest for 7 years, 216*7 should be the answer
So $1512
