Answer:
a= 8x+6x+48x+1
Step-by-step explanation:
Area of large rectangle is represented by a
a= 8x+6x+48x+1 - This is expanded form
Can be simplified to a= 62x+1
Step-by-step explanation:
ATQ,
Let d be the number of kilograms of dark chocolate she buys and m be the number of kilograms of milk chocolate she buys.
She needs to buy 120 kg of chocolate in total for her next order, and her recipe calls for twice the amount of dark chocolate as milk chocolate.
So,
m = 2d .....(1)
m + d = 120 ...(2)
We can also solve the above equations,
Put m = 2d in equation (2)
2d + d = 120
3d=120
d = 40
Put d = 40 in equation (1)
m = 2(40)
m = 80
Hence, she will need 40 kg of dark chocolate and 80 kg of milk chocolate.
No, on a number line, 1 would be the smallest, then 1.25 then 1.5 and then 1.6 and then 2.
Answer:
The numbers are 19,20 and 21
Step-by-step explanation:
Let
x -----> the first consecutive number
x+1 ---> the second consecutive number
x+2 --> the third consecutive number
we know that
x+(x+1)+(x+2)=60
Solve for x
3x+3=60
3x=57
x=19
so
x+1=19+1=20
x+2=19+2=21
therefore
The numbers are 19,20 and 21
Split the second term in 5x^2 + 23x + 26 into two terms
5x^2 + 13x + 10x + 26
Factor out common terms in the first two terms, then in the last two terms
x(5x + 13) + 2(5x + 13)
Factor out the common term; 5x + 13
<u>(5x + 13)(x + 2)</u>
