Answer:
Josh has played in 3 times as many as Lisa has.
Step-by-step explanation:
She mixed up multiplication and addition.
6+12=18
6*3=18
<span> (x + 3) • (x - 12)
</span>
The first term is, <span> <span>x2</span> </span> its coefficient is <span> 1 </span>.
The middle term is, <span> -9x </span> its coefficient is <span> -9 </span>.
The last term, "the constant", is <span> -36 </span>
Step-1 : Multiply the coefficient of the first term by the constant <span> <span> 1</span> • -36 = -36</span>
Step-2 : Find two factors of -36 whose sum equals the coefficient of the middle term, which is <span> -9 </span>.
<span><span> -36 + 1 = -35</span><span> -18 + 2 = -16</span><span> -12 + 3 = -9 That's it</span></span>
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -12 and 3
<span>x2 - 12x</span> + 3x - 36
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x-12)
Add up the last 2 terms, pulling out common factors :
3 • (x-12)
Step-5 : Add up the four terms of step 4 :
(x+3) • (x-12)
Which is the desired factorization
Final result :<span> (x + 3) • (x - 12)</span>
Answer:
174cm^2
Step-by-step explanation:
Given data
L=9m
W=5m
H=3m
The formula for the total surface area of a cuboid is
SA=2lw+2lh+2hw
substitute
SA=2*9*5+2*9*3+2*3*5
SA= 90+54+30
SA= 174cm^2
Hence the surface area is 174cm^2
Answer:
48 i think
Step-by-step explanation:
4 + 12/13 = 64/13
4 + 19/20 = 99/20
4 + 26/27 = 134/27
4 + 33/34 = 169/34
4 + 40/41 = 204/41
top: 64, 99, 134, 169, 204
bottom: 13, 20, 27, 34, 41
top:
35(1) + 29 = 64
35(2) + 29 = 99
35(3) + 29 = 134
35(4) + 29 = 169
35(5) + 29 = 204
bottom:
7(1) + 6 = 13
7(2) + 6 = 20
7(3) + 6 = 27
7(4) + 6 = 34
7(5) + 6 = 41
answer is C.
35n + 29
------------
7n + 6
