Answer:2 or 2/1
Step-by-step explanation:
Start a 0
Count up until the line perfectly hits in the center of the lines
Solve for x by simplifying both sides of the equation, then isolating the variable.
x = 15
Answer:
Length: 12
Width: 2
Area: 24
Step-by-step explanation:
We first find the points of C and D to find the length.
C: (-4,-5)
D: (2,-3)
The distance is 2
.
Now for the height.
A: (2,9)
D: (2,-3)
The distance is 12.
Area: 2×12 = 24
Answer to part A: 11w^2+7z^2
Answer to part B: 14w^2+9w
=================================================
Explanation:
For part A, the expression 4w^2+7w^2+7z^2 has one pair of like terms. That pair is 4w^2 and 7w^2 which combine to 11w^2. You add the coefficients to get 4+7 = 11, then tack w^2 onto everything to say 4w^2+7w^2 = 11w^2
We cannot combine 11w^2 and 7z^2 as they aren't like terms. So we leave it as 11w^2+7z^2
--------------------
In part B, the like terms are 15w and -9w. They combine to 15w-9w = 6w. You can think of it like 15-9 = 6 then stick a 'w' to each term. We cannot combine the w^2 term with the w terms.
Answer:
The value of x is <u>1</u><u>0</u><u>.</u>
Step-by-step explanation:
By question,
-4(x - 5) = 60
or,-4x + 20 = 60
or,-4x = 60 -20
or, -4x = 40
or, x =40/-4
Hence,x=10
