Answer:

Fact families and multiplication helps to divide . In any division problem, we use its divisor and check whether we get the dividend by multiplying a number to divisior.

For example:- Consider a division problem 40\div5

Here, Dividend= 40 and divisor = 5

Now, search the fact families of 5 which give 40 as an answer, we get

5\times8=40\ or\ 8\times5=40

\\\Rightarrow\ 40\div5=8

we can check our answer by multiplying divisor to the answer

5\times8=40

Bonjour, pouvez vous m'aidez svp ^^ Ci-contre, [MH] est une hauteur du triangle MAT. Éva affirme que le périmètre du triangle MA
Anna35 [415]

Cette question est incomplète.

Question complète

Exercer:

En face, [MH] est une hauteur du triangle MAT.

a.Calculer MH, puis HT.

b. Eva dit: "".

A-t-elle raison? Expliquer.

MA = 7,8cm

MT = 7,5cm

AH = 3cm

Answer:

La réponse d'Eva est incorrecte

Step-by-step explanation:

Nous résolvons les questions abive en utilisant le théorème de Pythagore

c² = a² + b²

a) Application de la formule ci-dessus:

Étape 1

Trouver MH

MA² = MH² + HA²

7,8² = MH² + 3²

MH² = 60,84-9

MH² = 51,84

MH = √51,84

MH = 7,2 cm

Étape 2

Résoudre pour HT

MT² = MH² + HT²

7,5² = 7,2² + HT²

HT² = 56,25 à 51,84

HT = √4,41

HT = 2,1 cm

b) La formule pour le périmètre du triangle MAT =

MA + MT + AH + HT

= 7,8 + 7,5 + 2,1 + 3 = 20,4 cm

Le périmètre du triangle MAT est de 20,4 cm

Donc, la réponse d'Eva est incorrecte

nexus9112 [7]

Answer:

Tina

Step-by-step explanation:

bc if you sub in 4 for x the equations on both sides are 0

check:

-4 + 4 = 0                         -3 x 4 = -12

0 x 3 = 0                          12 + -12 = 0

                    0 = 0
