Answer:
I will just choosé the second one
Because it is possible to compare sizes In one triangle rather than comparing with another one which we don't reàlly know of its sizes.
Answer:
(y − 9) (y − 2)
Step-by-step explanation:
Factor y^2 − 11y + 18 using the AC method.
(y − 9) (y − 2)
The “AC” method or factoring by grouping is a technique used to factor trinomials. A trinomial is a mathematical expression that consists of three terms.
Answer:
I believe it is 3.1875.
Step-by-step explanation:
25% of 2.55 is 0.6375.
2.55 + 0.6375 = 3.1875.
100%/x%=75/15
<span>(100/x)*x=(75/15)*x - </span>we multiply both sides of the equation by x
<span>100=5*x - </span>we divide both sides of the equation by (5) to get x
<span>100/5=x </span>
<span>20=x </span>
<span>x=20</span>
Answer:
A. in Step 3
Step-by-step explanation:
It is factored correctly. Then separated into two smaller equations correctly. But in solving x + 10 = 0, there is an error.
x + 10 = 0
Add -10 to both sides.
x = -10
So, the error is in step 3.
