for
ax=0
assume x and/or y=0
we have
(3)(-4)(x)=0
since
3≠0
-4≠0
thefor
x=0
answer is D
ok, so we now just have 4 normal sides and 2 L shapes
L shape can be cut into 2 rectangles
5 by 5 and 5 by 10 so total of 75 is the L
2 L's so
2*75=150
the sides
4 of them
they all are 10 by 3
10*3*4=120
answer is A
First you subtract 7 minus 19 and 7/8b minus 5/4b:
5/4b+7=7/8b+19
-7/8b -7/8b
5/4b+7=7/8b+19
-7 -7
3/8b=12
Then you divide 12 by 3/8:
b=32
Answer:
the answer is 50cm
Step-by-step explanation:
x=5
so 5+5 would be 10
so the long side would be 10 and the short side would be 5
so 5cmx10cm= 50cm
Answer:
70 degrees
Step-by-step explanation:
<u>Step 1: Make an equation</u>
<em>16 + 6x = 8x - 2</em>
<em />
<u>Step 2: Add 2 to both sides</u>
16 + 6x + 2 = 8x - 2 + 2
<em>18 + 6x = 8x</em>
<em />
<u>Step 3: Subtract 6x from both sides</u>
18 + 6x - 6x = 8x - 6x
<em>18 = 2x</em>
<em />
<u>Step 4: Divide both sides by 2</u>
18 / 2 = 2x / 2
<em>9 = x</em>
<em />
<u>Step 5: Find the measure</u>
8x - 2
8(9) - 2
72 - 2
<em>70</em>
Answer: 70 degrees
