Answer:
Step-by-step explanation:
Perimeter of a rectangle = 2L +2W
L is the length
W is the width
If the length of a rectangle is 2 cm less than 7 times the width, then;
L = 7W-2 .... 2
Substitute eqn into the formula for finding the perimeter
P = 2(7W-2)+2W
P = 14W-4+2W
P = 16W-4
If P =60cm
60 = 16W-4
16W = 60+4
16W = 64
W = 64/16
W = 4cm
Hence the width of the rectangle is 4cm
Since l = 7w-
l = 7(4)-2
L = 28-2
L = 26cm
You can proceed and draw a rectangle with the dimension of 4cm by 26cm
Answer - c </= 4 or c >/= -3
2c - 1 </ 7
2c - 1 + 1 </= 7 +1
2c </= 8
2c/2 </= 8/2
c </= 4
2c - 1 >/= - 7
2c - 1 + 1 >/= -7 + 1
2c >/= -6
2c/2 >/= -6/2
c >/= -3
Answer:
= 6
Step-by-step explanation:
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
Here a = 6 and r = 30 ÷ 6 = 5, thus
= 6
B, because
3/15=x/75
75/15=5
3*5=15
15 is your answer.
1. A (-4,2), B (-6,3), C (-4,6), D (1,4) 2. A (-4,-4), B (-6,-3), C (-4,0), D (-1,2) 3. (this part depends more on what your teacher wants for you) the quadrilateral flips over the y-axis and moves 6 down. hope this helps!
