Answer:
-22.22 + 14.652c +b
Step-by-step explanation:
9.4c−1.01∙(22b−5.2c)+b
WE need to simplify it by combining like terms
First multiply - 1.01 inside the parenthesis
-1.01 * 22= 22.22
-1.01 * (-5.2c)= 5.252c
9.4c− 22.22 + 5.252c +b
Combine like terms
9.4 c+ 5.252c= 14.652c
So the given expression becomes
-22.22 + 14.652c +b
Answer:
Trapezoid is correct.
Step-by-step explanation:
See figure.
H = 180 - (27+87)
= 180 - 114
= 66
<u>Answer</u>:
A.
<u>Step-by-step explanation:</u>
The formula for arc length is:
arc length = rθ
where:
r is the radius = 7 in
θ is the central angle in radians = 135 × = 3/4 π
Substituting these values into the formula:
arc length = 7 in × 3/4 π
=
Same as last time:
d^2=(x2-x1)^2+(y2-y1)^2
d^2=(6--1)^2+(-2-4)^2
d^2=7^2+(-6)^2
d^2=49+36
d^2=85
d=√85 (85=5*7 and both 5 and 7 are prime so √85 cannot be simplified any further)
The exact distance is √85 units.
