Sav [38]4 years ago
3 0

Answer:

(5x+3)(2x+4)=10x^2+26x+12

Step-by-step explanation:

You use FOIL (First, Outer, Inner Last)

First: 5x times 2x= 10x^2

Outer: 5x times 4= 20x

Inner: 3 times 2x= 6x

Last= 3 times 4

Combine 20x and 2x to get 26x

If A PQR = ASTU, which statement must be true?
Aleks [24]

Answer:

O A. PQ = SU

Step-by-step explanation:

When two triangles are congruent then by CPCTC,

their corresponding parts ( angles and sides )  must be congruent.

In triangles PQR and STU,

Side PQ, QR and RP are corresponding to the sides ST, TU and US respectively,

Also, angles P, Q and R are corresponding to angles S, T and U respectively.

Here, Δ PQR ≅ Δ STU,

Thus, by the above property,

PQ ≅ ST, QR ≅ TU and RP ≅ US,

∠P ≅ ∠T, ∠Q ≅ ∠T and ∠R ≅ ∠U

5-(n-4)= 3 (n + 2)<br> what does n equal
Amanda [17]

Answer:

The value of n in this equation is -3/4

Step-by-step explanation:

5 - (n - 4) = 3 (n + 2)

Distribute the negative to (n - 4) and distribute 3 to (n + 2).

5 - n + 4 = 3n + 6

Add 4 to -5.

9 - n = 3n + 6

Subtract 9 from 6.

-n = 3n - 3

Subtract 3n from n.

4n = -3

Divide 4 by -3.

n = -3/4

I don't really know what the question is that needs to be solved, but
here's a suggestion that might help:

Since there are seven days in a week, you could multiply 25 milligrams
by 7, and that will tell you the number of milligrams in a whole week.
