(2x² - 5) - (3x² + 4).

Pretend that there is a -1 in front of :(3x² + 4).

(2x^2-5)-1(3x^2+4)

2x^2-5-3x^-4

2x^2-3x^2-5-4

=-x^2-9

Answer: -x^2-9

8×4= (?×7)-(?×3) Can u sove the equation^

Marianna [84]

8*4 = 32

Now, we need to solve this:-

32 = (?*7) - (?*3)
32=8*7 - 8*3
32= 56 - 24
32 = 32

So our equation is:-

8*4 = (8*7) - (8*3)

Given: FPST is a trapezoid, FP=ST, m∠F=45°, PF=8, PS=10 Find: The midsegment MN.

kodGreya [7K]

Answer:

$4\sqrt{2}+10$

Step-by-step explanation:

In trapezoid FPST, FP=ST, then this trapezoid is isosceles, so

$m\angle F=m\angle T=45^{\circ}.$

Draw the height PH. Triangle FPH is right triangle with two angles of measure 45°. This means that FH=HP. By the Pythagorean theorem,

$FH^2+PH^2=PF^2,\\ \\2FH^2=8^2,\\ \\FH^2=32,\\ \\FH=4\sqrt{2}.$

Since trapezoid FPST is isosceles, the base FT hasthe length

$FT=2FH+PS=8\sqrt{2}+10.$

Then the length of the midline is

$MN=\dfrac{FT+PS}{2}=\dfrac{8\sqrt{2}+10+10}{2}=4\sqrt{2}+10.$

What is the factorization of the polynomial below? -3x^3+15x^2+42x

kherson [118]

Factoring out x

x(-3x^2+15x+42) now factor parenthetical expression

x(-3x^2+21x-6x+42)

x(-3x(x-7)-6(x-7))

x(-3x-6)(x-7) we can factor out -3 from first parentheses

-3x(x+2)(x-7)
