If your looking for the y-intercept it is 4
Answer:
351.48cm²
Step-by-step explanation:
Heron’s Formula
Find half the perimeter (30+30+26)/2=43
It’s the square root of each side subtracted from 43, multiplied together, times 43.
√(43-30)*(43-30)*(43-26)*43=√13*13*17*43=√=123539=351.481cm²
Answer:
It would be 7 inches long.
Step-by-step explanation:
If he stretched it out 2 times the current length that means that you need to multiply. 3 1/2 can be put into the calculator as 3.5. 3.5 multiplied by 2 equals 7.
Answer:
a = 7.21
Step-by-step explanation:
Remark
This just uses a^2 + b^2 = c^2. You know 2 of the three things there.
<em><u>Givens</u></em>
Solution
a^2 + b^2 = c^2 Substitute the givens
a^2 + 12^2 = 14^2 Expand
a^2 + 144 = 196 Subtract 144 from both sides
a^2 = 196 - 144 Collect like terms on the right
a^2 = 52 Take the square root of both sides.
sqrt(a^2) = sqrt(52)
a = 7.2111
a = 7.21 Answer
Answer:
X - 2.
Step-by-step explanation:
x - 2
----------------------------
x2 – x + 1 ) x3 – 3x2 + 3x – 2
x3 - x2 + x
-------------------
-2x^2 + 2x - 2
-2x^2 + 2x - 2
---------------------
