Answer:
Step-by-step explanation:
L=2W
P=2(L+W), given L=2W and P=126
2(2W+W)=126
6W=126
W=21 and L=42
Answer:
c.i^ 3
Step-by-step explanation:
i^7/i x i^3
i ^ 7 / i ^ 4
i^ 7 - 4
i^ 3
Slope intercept form is y=mx+b
m(slope)=1/2
(x,y)—->(-8,-4) so x=-8 and y=-4 substitute and solve for b
-4=1/2(-8)+b
-4=-4+b
+4=+4
0=b
Answer:
29
Step-by-step explanation:
Use PEMDAS
5^2 + 8 ÷ 2
25 + 8 ÷ 2
25 + 4
29
Answer:
A, C, E
Step-by-step explanation:
-4 + (4+5) = 5
A: (4 - 4) + 5 = 5, equivalent
B: (-4 - 4) + 5 = -3, not equivalent
C: -(4-4) + 5 = 5, equivalent
D: -(4) + (-4) + 5 = -3, not equivalent
E: -4 + 4 +5 = 5, equivalent
