Have you learned BPEMDAS? (Brackets, Parenthesis, Exponents, Multiplication, Division, Addition, and Subtraction) When simplifying an algebraic expression, the first thing you should start with is looking over the problem to see if there are brackets.
For example: 51(9 [33 - 27] + 18)
There are brackets. See that inside the two brackets that it says "33 - 27". Do it. You get 6.
Now this is the problem: 51(9 [6] + 18)
Now for the second step. Where are the parenthesis? You can see them. Inside it says "9 [6] +18". Since multiplication is always done before addition, do 9 [6] first. The answer is 59. Now this is the inside: "59 + 18". Find out the answer. It is 77.
Next step: 51(77)
What does a number right next to a parenthesized number mean? It means to <em>multiply.</em> So this is what you do: 51 x 77. And what's the answer? 3927.
So here you go! This is how to solve a simple algebraic expression. I hope you like this answer, please Brainliest me, and have a wonderful night! :D
Answer:
Complete question is attached with.
Both the triangles are congruent by ASA property of congruence and the segment RT is congruent to FD.
Step-by-step explanation:
From angle sum property of the triangle we can find the measure of the missing angles.
As for we can find which is
And for we can find which is
To find the congruence.
We see that and
Then along with
Between these two angles we have a segment that is equal in measure.
So two angles and a side in continuation, we can apply ASA property of congruence.
Now segment and segemnt are congruent as both the segment have equal measures on it.
So finally option A is the correct choice and both the triangles are congruent by ASA property.
And RT is congruent with FD.
F(x)=1-x² and g(x)=√(11-4x)
(g+f)(2)=>
1-(2)²+√(11-4(2))
=√3-3
(f/g)(-1)
(1-(-1)²)/(√(11-4(-1))
=0
(g-f)(-1)
√(11-4*-1)-(1-(-1)²
=√15
(g×f)(2)
1-(2)²×√(11-4(2))
-3√3
