<span>a. Using the ratio of the sides
12 cm and 16 cm</span>
x/20 = 12/16
x = (12(20)) / 16 = 15
b. Using the ratio of the sides 6 cm and 8 cm
x/20 = 6/8
x = (6(20)) / 8 = 15
c. The answer is the same since the ratio 12/16 and 6/8 is
both equal to ¾.

Answer:
15 > 3 + 2.15 M is the required inequality to represent how far Ronan can travel if he cant spend over 15 dollars on cab fare.
Step-by-step explanation:
Here, the total maximum allowance of Ronan for cab fare = $ 15
The fixed cab fare = $3
Also, the fare per mile traveled by cab = $2.15
Now, 1 miles traveled cost $2.15.
let us assume Ronan travels M miles in TOTAL.
So, the cost for M miles = M x ( Cost per mile) = M ( $2.15) = 2.15 M
Now, TOTAL FARE = FIXED CAB RATE + RATE paid for M miles
or, $15 = $ 3 + 2.15 M
Also, he can spend maximum of $15 on cab fare.
⇒ 15 > 3 + 2.15 M
Hence, 15 > 3 + 2.15 M is the required inequality to represent how far Ronan can travel if he cant spend over 15 dollars on cab fare.
Step-by-step explanation:
this is clearly not a linear sequence (the terms don't have the same difference).
so, it has to be a geometric sequence.
the common ratio is r.
s2 = s1 × r
16 = 64 × r
r = 16/64 = 1/4
control :
s3 = s2×r
4 = 16 × 1/4 = 4
correct.
Answer:
A=4, B=3, C=2, D=7 or A=2, B=7, C=4, D=3
Step-by-step explanation:
To factor this, you are looking for factors of 8×21 = 168 that have a sum of 34.
168 = 1×168 = 2×84 = 3×56 = 4×42 = 6×28 = 7×24 = 8×21 = 12×14
The sums of these factor pairs are 169, 86, 59, 46, 34, 31, 29, 26. The factor pair whose sum is 34 is 6×28. This means we can rewrite the expression as ...
8x² +28x +6x +21
Factoring by pairs gives ...
4x(2x +7) +3(2x +7)
(4x +3)(2x +7) ⇒ A=4, B=3, C=2, D=7 or A=2, B=7, C=4, D=3
