Answer:
A
Step-by-step explanation:
Answer:
3(4x - 1)
Step-by-step explanation:
Given
12x - 3 ← factor out the common factor of 3 from both terms
= 3(4x - 1)
Answer:
I think the correct answers are options 2 and 4.
Answer:
<h3><em>the </em><em>answer</em><em> </em><em>is </em><em>A</em></h3>
Step-by-step explanation:
8x+6is equivalent to-7(1-x)+x+13 because
-7(1-x)+x+13
we use-7to multiply the numbers in the bracket which is equal to -7+7x(minus ❌times minus =+)
-7+7x+x+13
collect like terms
7x+x+13-7=8x+6
answer is A
Answer:
1)b
2)d)80/360×36π≈25.12cm²
4)d)32.5
5)c)135°
6)d)4π/3
Step-by-step explanation:
1) because as we know
Circle equation
=(x-a)²+(y-b)²=r²
=(x-5)²+(y+1)²=36 (given)
=(x-(+5))²+(y-(-1))²=6²
So
C(5,-1)and r=6
2)as we know area of sector
=Theta/360×πr²
=80/360×6²π
80/360×36×3.14
80/10×3.14
=25.12
4)to figure out 4 we have to separate the shape into 2 parts
First semi-circul
Second rectangle
So the parameter of the shape
=Circumference of semi-circul + the parameter of the rectangle
=[10π×½+2(10+3.4)]-10 (as the dashed line is not a part of parameter)
=[15.7+26.8]-10
=32.5
5)3π/4
3×180/4
540/4
135
6)240°
240°×π/180°
4π/3
