Answer:
6x^2 -4x +8
Step-by-step explanation:
(6x^2 + 5) - (4x - 3)
Distribute the negative sign
(6x^2 + 5) - 4x + 3
Combine like terms
6x^2 -4x +5+3
6x^2 -4x +8
She put 12.8 in place of 11.9 in the formula of the triangle. Then the correct option is A.
<h3>What is Geometry?</h3>
It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
Regina’s work to find the surface area of a square pyramid from its net is shown below.
A square pyramid. The square base has side lengths of 9.4 inches. The triangular sides have a height of 11.9 inches.
Surface area of the pyramid = 4 [one-half (9.4) (12.8)] + 9.4² = 329 square inches
Then the error done by Regina will be
She should have used One-half (9.4) (11.9) to represent the area of a single triangle.
Then the correct option is A.

Imma just solve for f⁻¹(x) for this one
to solve fr the invers
replace f(x) with y
switch x and y
solve for y
replace y with f⁻¹(x)
I'm assuming your thing is

remember

translates to

so
if we replace y with f(x)

switch

translate

minus 4


evaluate



it equals 4

Answer:
In ΔABD and ΔAEC
BE=DC (given) …(i)
Subtracting DE from both side of (i), we get
BE–DE=DC–DE
BD=EC
AB=AC (given)
∠B=∠C (angle opposite to equal sides are equal)
Similarly, ΔABD≅ΔAEC
AD=AE (by c.p.c.t)
Hence proved
