Answer:
8
Step-by-step explanation:
1+3=4
5+7=12
12-4=8
Yes you use the method of your choice to solve (x+7)*(x+7)
Then you distribute the negative -1(x^2+14x+49)
Then you add the four
-x^2-14x-45 should be your answer

Step-by-step explanation:
Answer:
x = 70, y = 90
Step-by-step explanation:
A straight line is equal to 180 degrees, so if 180 is split between 110 and x. Subtract the 110 to get the rest. 180-110 = 70.
All sides in a quadrilateral add up to 360 degrees, add all of the remaining angles (112+88+70) to get 270. 360-270 = 90 degrees. Y is 90 degrees.
Answer:
x = 19
Step-by-step explanation:
you can set up a proportion among corresponding sides:
<u> 2x -14 </u> = <u> 18 </u>
32 24
18 /24 can be reduced to 3/4
<u> 2x - 14 </u> = <u> 3 </u>
32 4
cross-multiply: 4(2x - 14) = 32(3)
8x - 56 = 96
8x = 152
x = 19
