Answer:
Option C: 41
Step-by-step explanation:
<ABD+<CBD=90
<ABD=8x+1
<CBD=6x+5
(8x+1)+(6x+5)=90
Combine like terms
(8x+6x)+(1+5)=90
14x+6=90
14x=90-6
14x=84
divide both sides by 14
x=6
Now we plug that value into <DBC = 6x+5
6(6)+5=
36+5
41
Answer:
gradient = - 
, y- intercept = 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + 4y = 5 ( subtract 3x from both sides )
4y = - 3x + 5 ( divide terms by 4 )
y = - x + ← in slope- intercept form
with slope m = - and y- intercept c =
Answer:
1254.24
Step-by-step explanation:
Total area = sum of area of half circles and square
Area of square = 576
Area of half circles = 216π
So total area 576 + 216π
It says use 3.14 for π
So we get total area = 576 + 216(3.14)
==> multiply 216 and 3.14
total area = 576 + 678.24
==> add 576 and 678.24
total area = 1254.24
