Answer:
b=9
(assuming you meant -6x) x = -2
h = -4
a = 6
Step-by-step explanation:
Answer:
C = 6.28
A = 3.14
Step-by-step explanation:
use the equations for area and circumference to solve
C = pi d
A = pi r^2
I like to remember these using the saying Cherry pie's delicious, Apple pie's are too so Cherry = pi's delicious, Apple = pi's r 2
so with the diameter of 2 plug in to get circumference
C = 3.14 (2)
C = 6.28
and the equation for area uses radius not diameter but we know that d/2=r so radius is 1, plug in to solve
A = 3.14 (1)^2
A = 3.14 (1)
A = 3.14
Hope this helps! :)
Answer:
x=12
Step-by-step explanation:
Cross multiply them:
84 = 7x
Divide By 7 on both sides
12 = x
And there is the answer. Sorry I couldn't explain better Im really not feeling good today
See diagram
look a right triangle
for a right triangle
with legs legnth a and b and hypotonuse c
a²+b²=c²
so
the legs are 7 and the diagonal is c
a=b since all 4 sides of a square are equal legnth
7²+7²=c²
49+49=c²
98=c²
sqrt both sides
√98=c
(√49)(√2)=c
(7)(√2)=c
7√2=c
the legnth of the diagonal is 7√2 inches or aprox 9.899 inches
Answer:
2x+3x=150 ( sum of opposite interior angle of triangle is equal to the exterior angle)
5x=150
x=150/5
x=30
