4)
Area=(base x height) / 2
area=24 in²
therefore:
(b*3b)/2=24 in²
3b²/2=24 in²
b²=(24*2)/3 in²
b²=16 in²
b=√(16 in²)= 4 in
answer: 4 in
5)
if x=9
x²+z=103
(9)²+z=103
81+z=103
z=103-81=22
if x=-9
(-9)²+z=103
81+z=103
z=103-81=22
Answer: 23
1)

n=⁺₋√49=⁺₋7
Answer: ⁺₋7
2)
x²+64=0
x²=-64
x²=⁺₋√-64 These numbers are not real.
Answer:no solution
3)
area=slide²
slide=+√area
slide=+√(144x²)=12x
answer: 12 x
Answer:
m= 1/10
Step-by-step explanation:
1. Move the terms so that will be 3m - 2m=-1/2 + 3/5
2. Subtract the m values so that will be 3m - 2m= 1 or m
3. Calculate the sum.
4. So the answer will be m= 1/10. M because we subtracted 2 from 3 which make us 1 so we say it m and 1/10 by doing 1/2 + 3/5.
The coordinate pair can be obtained from the given equation by
rearranging the equation to make <em>y</em> the subject of the equation
- The table of values obtained from the given equation is presented as follows;
- The graph showing the points in the above table is attached
Reason:
The given equation is presented as follows;
2·x - 4·y = 12
(a) The values are found by making either <em>x</em>, or <em>y</em> the subject of the
formula, and inputting values as follows;
2·x - 4·y = 12
= 4·y
4·y = 2·x - 12

The rearranged equation is therefore
Plugging in values of <em>x</em>, (0, 1, 2, 3) to find the corresponding y-values gives;
x = 0
x = 3
x = 4
<u>The table of values</u> is therefore;
![\begin{array}{|c|cr|} \mathbf{x}&&\mathbf{y}\\0&&-3\\1&&-2.5\\2&&-2\\3&&-1.5\\4&&-1\end{array}\right]](https://tex.z-dn.net/?f=%5Cbegin%7Barray%7D%7B%7Cc%7Ccr%7C%7D%20%5Cmathbf%7Bx%7D%26%26%5Cmathbf%7By%7D%5C%5C0%26%26-3%5C%5C1%26%26-2.5%5C%5C2%26%26-2%5C%5C3%26%26-1.5%5C%5C4%26%26-1%5Cend%7Barray%7D%5Cright%5D)
