Answer:
6*1/2*7
=21
Step-by-step explanation:
a=3
a6=43
a+6d=43---------1
substituting a=3 in eq 1
a+6d=43
3+6d=43
6d=43-3
d=40/6
d=20/3
so first 5 no's are a, a+d, a2+d,a3+d, a4+d
a=3
a+d=3+20/d
i think u know after this
Hope it helps u
mark me as brainest if it helps u
Answer:
1. b. 4/7
2. c. 3
Step-by-step explanation:
To find the slope
m = (y2-y1)/(x2-x1)
m= (7-3)/(5 - -2)
= (7-3)/(5+2)
= 4/7
m = (y2-y1)/(x2-x1)
m= (5-2)/(2 - 1)
= 3/1
Answer:
letter A
Step-by-step explanation:
This is made up of 4 triangular segments. If we assume the cross section is perpendicular then we can use the 1/2b*h formula for each piece with the given values. So we have 2 triangles with the formula: 1/2(3)*(4.5)=6.75 * 2 triangles = 13.5.
Then for the bottom 2 you have 1/2(3)*7.5=11.25, times 2 triangles =22.5
So, 13.5+22.5=36, or letter A
Answer:
- <u><em> 3 + 6 = 9</em></u>
- <u><em>2 + 1 + 4 + 2 = 9</em></u>
- <u><em>18 : 2 = 9</em></u>
- <u><em>3 + 3 + 3 = 9</em></u>
Step-by-step explanation:
Which expression is equivalent to
(3²)
3² = 9
- 2 + 1 + 4 + 2 = 9
- 18 : 2 = 9
- 3 + 3 + 3 = 9
