1) factorised is (x+4)(x+1)=0
So x=-4 x=-1
2) factorised is (a-4)(a-3)=0
So a=4 a=3
(972.41 + 1,620) =
2592.41
2592.41 ×

=
51.8482
So, that means that your answer would have to be:
51.8482Just change "

" to
0.02 and by the way lineup the decimals and do P.E.M.D.A.S

Answer:
115 in²
Step-by-step explanation:
SA = Area of triangular surfaces + area of the square base
SA= 2bh + b²
SA = 2(5)(9)+5²
SA = 90+25
SA = 115
Answer:
Only B
Step-by-step explanation:
A has 2 pairs with the x as the number 2, so they are not functions.
B has all independent pairs with their own numbers
So only B is the correct answer.

Answers: Choice B and Choice D</h3>
==========================================================
Explanation:
Standard form will always have the largest exponents listed first on the left side. Then as you move to the right, the exponents will decrease. Choice B shows this with the exponents counting down (3,2). Choice D is a similar story with the exponents counting down (9,2,1,0). Think of -6x as -6x^1, and also think of the 10 as 10x^0.
Something like choice A is a non-answer because the term with the largest exponent 3 is buried in the middle, and not at the left side. The exponents are not in decreasing order. Choice C can be ruled out for similar reasons.
Side note: the largest exponent is the degree of the polynomial. This only applies to single variable polynomials.
