Answer:
16+5w
Step-by-step explanation:
2(5 + w) + 3(w + 2)
5+w evaluates to 5+w
Multiply 2 by 5+w
we multiply 2 by each term in 5+w term by term.
This is the distributive property of multiplication.
Multiply 2 and 5
1
2 × 5 = 10
Multiply 2 and w
Multiply 1 and w
The w just gets copied along.
w
2 × w = 2w
2*(5+w) evaluates to 10+2w
w+2 evaluates to w+2
Multiply 3 by w+2
we multiply 3 by each term in w+2 term by term.
This is the distributive property of multiplication.
Multiply 3 and w
Multiply 1 and w
The w just gets copied along.
w
3 × w = 3w
Multiply 3 and 2
1
3 × 2 = 6
3*(w+2) evaluates to 3w+6
To add the polynomials 10+2w and 3w+6 we try to add or combine terms in one polynomialwith any like terms in the other polynomial.
10 + 6 = 16
2w + 3w = 5w
The answer is 16+5w
2*(5+w)+3*(w+2) evaluates to 16+5w
The final answer is
16+5w
Okay, first thing first... you are amazing
second, number 7 is 5/2
number 10 is 3/6
hope this helps and have a w-o-n-d-e-r-f-u-l d-a-y :)
and merry christmas
The 4 tells you how much 0 you have so you have 4 zeros your number will be10000 and you multiple 10,000 Times 20 hopes I helped
Speed of student A is 180 ft/min
Speed of student B is 120 ft/min
Relative speed=(120+180)=300 ft/min
Distance between them is 2420 ft
Time taken for them to meet will be:
time=distance/speed
=(2420-20)/300
=8 min
Answer: A.) b= 2a/h-c
1/2h(b+c)= A
2×1/2h(b+c)=A×2
h(b+c)=2A
h÷h(b+c)=2A÷h
b+c=2A/h
b+c-c=2A/h-c
b=2A/h-c
I hope this is good enough:
