Answer:
7x^2 (the first choice)
Step-by-step explanation:
7x^2
4x+3x = 7x
(4+3)x = 7x
7x
All are 7x except for the first one which is 7x^2
Width = w
length = w + 10
perimeter 2w+2l=184
2w + 2(w+10) = 184
2w + 2w + 20 = 184
4w = 164
w = 164/4 = 41
w = 41
l = 51
Area = wl
Area = 41×51 = 2091 Sq ft
Answer:
-2
Step-by-step explanation:
We can find the slope by using the slope formula
m = (y2-y1)/(x2-x1)
= (-5 - -7)/ ( -2 - -1)
= ( -5+7) / ( -2 +1)
= 2/-1
= -2
Answer:
95°
Step-by-step explanation:
(x+49)+(x+59)=180
2x+108=180
2x=72
x=36
36+59=95
the mean can be misleading, because there outlier (77), which is not close to the ages of the others, thereby changing the mean drastically.
hope this helps
