The answer is 20
Hope this helps!
Step-by-step explanation:
a) Perimeter is equal to 2w + 2L
2(3x + 4) + 2(x + 3)
6x + 8 + 2x + 6
8x + 14
b) Put 5 in x's place
8×5 + 14
40 + 14
54
c) Area = (3x + 4) * (x + 3)
Put 4 in x's place
(3×4 + 4) * (4 + 3)
12 + 4 * 7
16 * 7
112
I have seen you ask this question twice before, so I will give you the answer that HugoD gave you:
In mathematics, "of" is translated as a multiplication.
So, you have :
.
Answer: Equation: 0.5*30*b = 210
Base length: 14
Step-by-step explanation: The formula of the area of a triangle is 1/2*b*h, so we can use that and the information given to make a formula then solve.
Answer: The distance between a and c is 8 units
Step-by-step explanation:
You can count the number of units they are apart, but if there isn’t a grid, then do this:
If x or y values in the ordered pairs are different, subtract them from each other and find the absolute value of the difference. (It’s my own rule, so there is a better method. My explanation apples only to ordered pairs that share a x or y value, like A and C)
2-(-6) = 8, and the absolute value of 8 is 8
Or
(-6)-2 = (-8), and the absolute value of -8 is 8 (You’ll get the same answer)
